Question

1. an electrician charges $60 per hour on top of a set fee of $50 for every house call. write an equation for c, in terms of t, representing the total cost of the electricians services if the electrician spends t hours at the house working.

Explanation:

Step1: Identify fixed and variable costs

The set fee (fixed cost) is $50. The variable cost is $60 per hour, so for \( t \) hours, it's \( 60t \).

Step2: Formulate total cost equation

Total cost \( C \) is fixed cost plus variable cost: \( C = 50 + 60t \).

Answer:

\( C = 60t + 50 \)
