Write an expression to represent each electricians total charge

Question

Flash Electricians

Call out charge = $50

Hourly charge = $50

Answer 1

Total Cost = Fixed Cost + Variable Cost

Define the variable: Let x = the number of hours worked.

In this case, the fixed cost is the call out charge. No matter how much time they work, it will cost you $50 for them to come to your house. The variable cost is the hourly change. It will depend on how many hours they spend working at your house.

Total cost = 50 + 50x

Answer 2

Hi Ronia B,

I fully agree with Denise G's answer. Based on the hourly use, x, you can determine the total cost by calculation of Total cost = 50 + 50x.
