Tara Clayton · Answer 1

c 17

Step-by-step explanation:

You make 23 a day plus 3.60 per sale

Income = 23 + 3.6 s

You want to make at least 84

84 ≤ 23 + 3.6 s

Subtract 23 from each side

84 - 23 ≤ 23-23 + 3.6s

61 ≤ 3.6s

Divide by 3.6 on each side

61/3.6 ≤ 3.6s/3.6

16.94444 ≤ s

You must make more than 16.94444 sales

But you cannot make part of a sale so

You must make at least 17 sales
