Question

Kelly wants to make a fruit salad made up of bananas, apples, and peaches. She wants to mix one part apples, 2 parts peaches, and 3 parts bananas. Bananas cost $2.00 per pound, apples cost $4.00 per pound, and peaches cost $5.00 per pound. Kelly only has $10.00, and will spend it all on fruit salad. Write an equation and use this equation to determine how many pounds of fruit salad he can make.

Answer 1

Explanation:

If x is the pounds of apples, 2x is pounds of peaches, and 3x is pounds of bananas, then the total cost is:

4(x) + 5(2x) + 2(3x) = 10

4x + 10x + 6x = 10

20x = 10

x = 0.5

Kelly buys 0.5 pounds of apples, 1 pound of peaches, and 1.5 pounds of bananas, for a total of 3 pounds of fruit.
