As a salesperson you get $23/ day and $3.60/each sale you make. if you want to make at least $84. in one day, how many sales would need to make? a 15b 16c 17d 18

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

345
