An internet service provider charges $9.95/ per month for the 1st 20 hrs?

Question

and $.50 for each additional hours. Write an expression representing the charges for h hours of use in 1 month when h is more than 20 hours. What is the charge for the 35 hours?

Answer 1

$9.95 + $0.50 x (h - 20)

$17.45

Answer 2

First 20 hrs=9.95
Every additional hr=.50
When h is greater than 20 hrs,
Charges=9.95+.50(h-20)
For 35 hrs, C=9.95+.50(35-20)
C=9.95+.50(15)
C=9.95+7.50
C=17.45

Answer 3

Let h = no. of hours

Answer: $9.95 + $0.50(h - 20)

= $9.95 + $0.50(35 -20)
= $9.95 + $0.50(15)
= $9.95 + $7.50
= $17.45

Answer: $ 17.45
