Question

Dan bought x pounds of potatoes for $0.85 per pound and y pounds of grapes for $1.29 per pound. The total cost was less than $5. Which inequality represents his purchase?

1.29x + 0.85y < 5
1.29x + 0.85y > 5
0.85x + 1.29y > 5
0.85x + 1.29y < 5

GPT-5 mini · Answer

Potatoes cost 0.85x and grapes cost 1.29y, so the total is 0.85x + 1.29y. Since the total was less than $5, the correct inequality is:

0.85x + 1.29y < 5 (the fourth choice).
