An electrician charges a set fee of $150 for every house call and then charges an additional $70 per hour. Write an equation for C, C,C, in terms of t, t,t, representing the total cost of the electrician's services if the electrician spends ttt hours at the house working.

C = 70t + 150

Step-by-step explanation:

Since they charge $70 per hour and t represents the number of hours worked, the cost of the services alone can be represented by 70t.

There is a $150 set fee, so add this to 70t:

70t + 150 represents the total cost.

To create the equation, set this equal to C, the total cost:

C = 70t + 150 is the equation
