juan spent at most $2.50 on apples and oranges. He bought 5 apples at $0.36 each. What is the most he spent on the oranges?

Question

Solve this please! It doesn't make any sense to me, if able to also write it step by step that would be great too.

Answer 1

Hi Emily W

Let x = apples

Let y = oranges

We know apples cost 0.36 and that 5 apples were purchased

We also know that $2.50 at the most was spent on apples and oranges so we have

5x + y <= 2.50

We can substitute the given values for x and set the equation equal to 2.50 to solve for y

5(0.36) + y = 2.50

1.80 + y = 2.50

y = 2.50 - 1.80 = 0.70

Since seventy cents was left over for oranges that is the most that could be spent on oranges

I hope this helps.
