Bobby and $9 per hour and $6 for each delivery he makes. He wants to earn more than $155 an 8 hour work day. What is the least number of deliveries that Bobby must make to reach his goal?

Solution:

Given that,

Bobby per $9 per hour and $6 for each delivery he makes

Let "D" be the number of delivery he makes

He wants to earn more than $155 an 8 hour work day

Thus a inequality is framed as:

Subtract 72 from both sides

72 + 6D - 72 > 155 - 72

6D > 83

Divide both sides by 83

D > 13.83

Thus least number of deliveries that Bobby must make to reach his goal is 14
