4. A local Internet provider offers a plan

in which you pay a flat fee of $5.95 per
month plus $0.20 per hour of use.
For how many hours of use were you
billed if your monthly bill is $8.95?

Answer:

15 hours

Explanation:

If you use the slope intercept form (y = mx + b), the equation for the internet provider would be:

f = 0.20h + 5.95

where f = the fee, and h being the hours.

8.95 - 5.95 = 3

3 / 0.2 = 15 (hours)

You would need to have 15 hours of use if your monthly bill was $8.95.
