Question

Ben earns $9 per hour and $6 for each delivery he makes. He wants to make $155 in an 8-hour workday. What is the least number of deliveries he must make to reach his goal?

Answer 1

To first get rid of the $9 per hour do 8 x 9 (=72). Then do 155- 72 (=83)to show how much more money needs to be made, then 83/the amount of money for each delivery- which is 6. Then the answer is rounded up from 13.83333 to 14 and the answer is 14.

Answer 2

find how much he will earn
we know he will earn 8 hours sofirst find how many he earns
9 per hour
8 hou
9*8=72
72+6*numberofdeliveries=155
minus 72
6*numberofdeliviers=83
divide by 6
number of delevieries=13.8
he can't make 13.8, round up to get 14

answer is 14 deliveries
