Answer:
c 20
Step-by-step explanation:
You make 53 a day plus 3.75 per sale
Income = 53+ 3.75 s
You want to make at least 128
128 ≤ 53+ 3.75 s
Subtract 53 from each side
128 -53 ≤ 53-53 +3.75s
75≤ 3.75s
Divide by 3.75 on each side
75/3.75≤ 3.75s/3.75
20 ≤ s
You must make at least 20 sales

because 0.17 is how much he has to pay for each message sent and if x is the total messages he sends then it should be 0.17X+24.07
2x+3+51 = 100
2x+54=100
2x= 46
X=23
