Joshua earns $9 per hour and $6 for each delivery he makes. he wants to earn more than $155 in a 8-hour workday. what is the least amount of deliveries he must make to reach his goal?

Answer to your question:

Let no. of hours Joshua works be x
no. of he makes be y

Money he earns=9x+6y

According to question,

9 (8)+6y>155
72 +6y>155
6y>155-72
6y>83
y>83/6
y>13.8

So, Joshua must do atleast 14 deliveries to reach his goal.

Hope it helps ^_^
