Step-by-step explanation:
It seems like bobby has a bad paying job but lets start
Lets do math:
this is our equation:
155=8·9+6x
155-72=83
so now we have to see how many deliveries he has to make to get 83
83/6=13 endless number
lets approximate the amount of deliveries to 14
he has to make at least 14 deliveries to reach his goal.
