Question

9) Craig earns the same amount

Answer 1

Answer:

Craig earns $1,200 each month

Explanation:

We are given that Craig pays a total of $720 each year for his telephone service

We also know that a year has 12 months

This means that:

Craig pays $\frac{720}{12}= 60$ dollars each month for his telephone services

We are given that the monthly phone bill is $\frac{1}{20}$ of his monthly earnings

Assume that his monthly payment is x

We have:

$\frac{1}{20}x = PhoneBill\\ \\ \frac{1}{20}x = 60\\ \\ x=60*20 = 1200$ dollars

Hope this helps :)
