Answer:

18 hours

Explanation:

Let the number of hours used to represented by x

Gloria subscribes to the Webtime Internet Service. Webtime charges a $9.99 monthly service fee plus $1.50 per hour for Internet access.

Total bill = $9.99 + $1.50 × x

= 9.99 + 1.5x

Last month's bill was $ 36.99.

Hence,

9.99 + 1.5x = 36.99

Collect like terms

1.5x = 36.99 - 9.99

1.5x = 27

x = 27/1.5

x = 18 hours

The number of hours that Gloria used the Internet last month is 18 hours
