Question

Ben earns $10 per hour and $6 for each delivery he makes. He wants to earn more than $155 in an 8-hour workday. What is the least number of deliveries he must make to reach his goal? a) Write an inequality to model the situation. Use d to represent the number of deliveries

Answer 1

the number of deliveries would be 13

And, the equation is d ≥ 12.50

Explanation:

The inequality function is given below:

Let us assume the d be the number of deliveries

10 × 8 + 6 × d ≥ 155

80 + 6d ≥ 155

6d ≥ 155 - 80

6d ≥ 75

d ≥ 75 ÷ 6

d ≥ 12.50

hence, the number of deliveries would be 13

And, the equation is d ≥ 12.50
