Question

Phil is baking a pie with cranberries and apples. Apples cost $0.60/cup and cranberries cost $0.40/cup. Phil wants to spend no more than $4.20 on the fruit for his pie.

Question
What is an inequality that represents the combinations he can use?

Answer 1

Let a be the number of cups of apples and c be the number of cups of cranberries. An inequality that represents the combinations Phil can use is:

0.6a + 0.4c <= 4.2

This inequality ensures that the cost of the fruit used for the pie is no more than $4.20.
