Question

Bobby earns $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?

Answer 1

Answer: 14

Explanation:
9*8=72
You have to multiply the 9 per hour times the 8 hour work day.
155-72=83
We have to get $83 in deliveries.
83/6=13.8333...
The $83 dollars we have to earn in deliveries divided by the $6 we earn for each delivery equals 13.8333...
This means that Bobby must at least have 14 deliveries to reach his goal. (You can’t have a fraction of a delivery)
