Step-by-step explanation:

We know that:

So, using this data we can form the relation for the problem:

; where b is the unknown fixed fee.

Solving for b:

With this result, the explicit linear equation would be:

; where x is hours and y is the total cost.

For 10 hours would be:

Therefore, for 10 hours the charge is $180.
