Answer 1

Answer:

a 3

Step-by-step explanation:

You make 50 a day plus 3.60 per sale

Income = 50+ 3.6 s

You want to make at least 60

60 ≤ 50+ 3.6 s

Subtract 50 from each side

60 -50 ≤ 50-50 +3.6s

10 ≤ 3.6s

Divide by 3.6 on each side

10/3.6 ≤ 3.6s/3.6

2.7777777 ≤ s

You must make more than 2.7777 sales

But you cannot make part of a sale so

You must make at least 3 sales
