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

Explanation:

Step1: Calculate potato cost

Cost of potatoes: $0.85x$

Step2: Calculate grape cost

Cost of grapes: $1.29y$

Step3: Set total cost inequality

Total cost < 5, so $0.85x + 1.29y < 5$

Answer:

D. $0.85x + 1.29y < 5$
