Melissa buys 2 1/2 pounds of salmon and 1 1/4 pounds of swordfish. She pays a total of $31.25, and the swordfish costs $0.20 per pound less than the salmon. What would be the combined cost of 1 pound of salmon and 1 pound of swordfish? A. $15.60 B. $15.80 C. $16.60 D. $16.80
We are required to find the cost of 1 pound of salmon and 1 pound of swordfish
The cost of 1 pound of salmon and 1 pound of swordfish is $16.60
let
cost of a pound swordfish = x
cost of a pound salmon = y
x = y - 0.20. (1)
2.5y + 1.25x = 31.25. (2)
Substitute x = y - 0.20 into (2)
2.5y + 1.25x = 31.25
2.5y + 1.25(y - 0.20) = 31.25
2.5y + 1.25y - 0.25 = 31.25
2.5y + 1.25y = 31.25 + 0.25
3.75y = 31.5
y = 31.5 / 3.75
y = 8.4
Recall,
x = y - 0.20. (1)
x = 8.4 - 0.20
x = 8.2
Therefore, the cost of a pound swordfish, x is $8.2 and cost of a pound salmon, y is $8.4
Total cost of 1 pound of salmon and 1 pound of swordfish = $8.4 + $8.2
= $16.6

Luis has 3 pounds of ground turkey to make burgers. He uses 3/8 pound per burger to make 6 burgers. How many 1/4 pound burgers can Luis make with the remaining turkey?
Final answer:
With the remaining 3/4 pound of turkey, after converting to ounces, Luis can make 3 additional 1/4 pound burgers.
Explanation:
Luis has 3 pounds of ground turkey and makes 6 burgers using 3/8 pound of turkey per burger. To find out how much turkey he used, we multiply the number of burgers by the weight of turkey per burger:
6 burgers × 3/8 pound/burger = 18/8 pounds = 2 1/4 pounds
Now, subtract the amount used from the initial amount to find the remaining turkey:
3 pounds - 2 1/4 pounds = 3/4 pound remaining
To convert pounds to ounces (as there are 16 ounces in a pound), multiply 3/4 pound by 16:
(3/4) × 16 = 12 ounces remaining
To determine how many 1/4 pound burgers Luis can make, we convert the quarter pounds to ounces, which is 4 ounces per burger, and then divide the remaining ounces by 4:
12 ounces / 4 ounces/burger = 3 burgers
Therefore, Luis can make 3 more 1/4 pound burgers with the remaining turkey.

a bowling ball has a mass of 5.54 kg. A bowling pin has a mass of 1.58 kg. About how many pins are equal in mass to one ball
To find the number of bowling pins equal in mass to one bowling ball, divide the mass of the ball by the mass of one pin. Approximately 4 pins are equal in mass to a 5.54 kg bowling ball.
To find how many bowling pins are equal in mass to one bowling ball, we divide the mass of the bowling ball by the mass of a single pin. This gives us the number of pins that would have a combined mass equal to the mass of the ball.
Mass of bowling ball = 5.54 kg
Mass of one pin = 1.58 kg
We calculate the number of pins as follows:
Number of pins = Mass of bowling ball / Mass of one pin
Number of pins = 5.54 kg / 1.58 kg
Number of pins ≈ 3.51
Since the number of pins must be a whole number, we would say that approximately 4 pins are equal in mass to one bowling ball.

Find p+q, given that (q+4)(p+3)-(q+2)(p+1)=44.
We find that p+q = 17.
To find p+q, we need to solve the given equation step by step:
(q+4)(p+3) - (q+2)(p+1) = 44
Expanding both products, we get:
qp + 3q + 4p + 12 - qp - q - 2p - 2 = 44
We notice here that the 'qp' terms cancel each other out. Simplifying, we are left with:
2q + 2p + 10 = 44
Subtracting 10 from both sides gives:
2q + 2p = 34
Divide by 2:
q + p = 17
Therefore, p+q = 17.

An apple pie uses 4 cups of apples and 3 cups of flour. An apple cobbler uses 2 cups of apples and 3 cups of flour. You have 16 cups of apples an 15 cups of flour. When you sell these at the Farmers market you make $3.00 profit per apple pie and $2.00 profit per apple cobbler. Use linear programming to determine how many apple pies and how many apple cobblers you should make to maximize profit.
Attached first is what I have so far. Attached second is what I need help with. How to I write an obgective function that I can use to evaluate the profit?
let x = number of apple pies you would make
let y= the number of apple cobblers you make
4 cups of apples
for a pie 2 cups for cobbler with 16 cups
so we have: 4x+2y<=16
3 cups of flour for both pies and cobbler we get: 3x+3y<=15.
solve the system of inequalities to get (3,2)
check: 4(3) +2(2) = 12+4 = 14, this is less than 16 so this is true
3(3) + 3(2) = 9 +6 = 15 does equal 15 so this is true
Now profit equation is 3x +2y = profit
3(3) +2(2) = 9+4 = 13
You can make 3 apple pies and 2 apple cobblers for maximum profit
In this exercise we have to have knowledge about finances, in order to be able to calculate and write a function that corresponds to profits, so:
[tex]3x +2y = profit[/tex]
Then using the information given in the text we can write that:
let x = number of apple pies you would makelet y= the number of apple cobblers you make4 cups of apples for a pie 2 cups for cobbler with 16 cupsSo writing the function we have that corresponds to:
[tex] 4x+2y\leq 6[/tex]
So writing the second function that corresponds to 3 cups of flour, we have:
[tex]3x+3y\leq 15[/tex]
So solving these systems we find:
[tex] 4(3) +2(2) = 12+4 = 14\\ 3(3) + 3(2) = 9 +6 = 15\\ 3x +2y = profit[/tex]

Number of crates (n) 2 4 6 8
Cost ($) $25 $45 $65 $85
We can write the equation as -
y = mx + c
y = {(45 - 25)/(4 - 2)}x + c
y = 10x + c
c = 25 - 10 x 2
c = 5
Therefore, the equation representing the Manuel's situation is -
y = 10x + 5

Marsha practiced the flute for double the minutes Sílvio practiced. Together they practiced for 90 minutes. How long did each student practice?
To find out how long Marsha and Sílvio practiced, we set up the equation x + 2x = 90, where x is the time Sílvio practiced. Solving the equation, we found that Sílvio practiced for 30 minutes and Marsha for 60 minutes.
The question asks us to solve for the amount of time Marsha and Sílvio each practiced their instruments given that Marsha practiced for twice the time that Sílvio did and together they practiced for a total of 90 minutes.
Let's denote the time Sílvio practiced as x minutes. This means Marsha practiced for 2x minutes. We know that the sum of their practice times is 90 minutes, which gives us the equation:
x + 2x = 90
Combining like terms, we have:
3x = 90
Dividing both sides by 3 to solve for x gives:
x = 30
Therefore, Sílvio practiced for 30 minutes and Marsha practiced for 60 minutes (double the time of Sílvio).

How many ants does it take to have the same mass as an elephant
Final answer:
To equal the mass of an elephant weighing 8 metric tons, it takes approximately 2 billion ants, each weighing 4×10^-3 grams.
Explanation:
The question asks how many ants would equal the mass of an elephant when the mass of an ant is approximately 4×10^-3 grams and the mass of an elephant is about 8 metric tons. First, we need to convert the mass of the ant into the same units as the elephant's mass. Since there are 1,000 grams in a kilogram and 1,000 kilograms in a metric ton, we can calculate the mass of the ant in metric tons as 4×10^-3 grams × (1 kilogram / 1,000 grams) × (1 metric ton / 1,000 kilograms), which simplifies to 4×10^-9 metric tons. To find the number of ants needed to equal the mass of an elephant, we divide the elephant's mass by the mass of one ant: 8 metric tons / 4×10^-9 metric tons per ant = 2×10^9 ants. Therefore, it takes approximately 2 billion ants to have the same mass as an 8 metric ton elephant.
