Answer:
Step-by-step explanation:
1. **Identify the costs:**
- Dan bought x pounds of potatoes at $0.85 per pound.
- Dan bought y pounds of grapes at $1.29 per pound.
2. **Calculate the total cost:**
- The cost of the potatoes is 0.85 times x .
- The cost of the grapes is 1.29 times y .
- Therefore, the total cost is 0.85x + 1.29y .
3. **Determine the condition:**
- The total cost is less than $5.
- This can be expressed as 0.85x + 1.29y < 5 .
4. **Construct the inequality:**
- The inequality representing the total cost being less than $5 is:
0.85x + 1.29y < 5
So, the correct inequality that represents Dan's purchase is:
0.85x + 1.29y < 5
