Question

Brad earns $12 per hour and $7 for each delivery he makes. He wants to earn more than $205 in a 8-hour workday. What is the least number of deliveries he must make to reach his goal?

Answer 1

16

Explanation:

Earnings = 12h + 7d

(h is hours and d is deliveries)

205
`\geq` 12(8) + 7d

205
`\geq` 96 + 7d

109
`\geq` 7d

15.57
`\geq` d

round up ⇒ 16
