You manage an ice cream factory that makes two flavors: Creamy Vanilla and Continental Mocha. Into each quart of Creamy Vanilla
nadezda [96]

Answer:

You should make 150 quarts of Creamy Vanilla and 50 quarts of Continental Mocha.

Step-by-step explanation:

This problem can be solved by a system of equations.

The largest profit is going to earned when all the eggs and cups of cream in stock are used.

I am going to call x the number of quarts of Creamy Vanilla and y the number of quarts of Continental Mocha.

The problem states that each quart of Creamy Vanilla uses 2 eggs and each quart of Continental Mocha uses 1 egg. There are 350 eggs in stock, so:

2x + y = 350

Each quart of Creamy Vanilla uses 3 cups of cream, as does each quart of Continental Mocha. There are 600 cups of cream in stock.

So:

3x + 3y = 600 Simplifying by 3.

x + y = 200

We have the following system

1)2x + y = 350

2)x + y = 200

I am going to multiply 2) by (-1) and then add with 1), so i can eliminate y

1)2x + y = 350

2)-x - y = -200

2x - x + y - y = 350 - 200

x = 150

x + y = 200

y = 200 - 150 = 50

You should make 150 quarts of Creamy Vanilla and 50 quarts of Continental Mocha.

Answer:

-6x+2y=-18 = y = -9 + 3x

-3x-2y=54 = y = -27 - \frac{3x}{2}
