Answer:

D. 14

Step-by-step explanation:

Write the expression (explanation)

9 per hour= 9xh= 9h

and= addition

6 each delivery= 6xd=6d

more than= >

Final expression you need to solve

9h+6d>155

how many hours?: 8 hours

9(8)+6d>155

solve for d

72+6d>155

6d>83

d>~13.83

He cannot make less than 13.83, so you would round it up to 14.

Answer:

14 deliveries

Step-by-step explanation:

First we have to find out how much he makes in a day aside from what he makes a day aside from his deliveries, so 9 x 8 = 72. Then we take 155 - 72 = 83. Then since he wants to make more than 155, we'll add one to 83, then take that divided by 6.  84/6=14. So he'd have to make at least 14 deliveries to make $156 in a day.
