Answer:the two different ways that the total charges can be represented are

79 + 69x

79 + 84x

Step-by-step explanation:

Let x represent the number of hours that the Plumber is hired by the customer.

A plumber charges a customer a one time service fee of $79, then $69 per hour for labor and a surcharge of $15 per hour due to the call being an emergency. This means that

1) if the call was not an emergency, there would be no surcharge. Therefore, the total charge for x hours would be

79 + 69x

2) if the call was an emergency, there would be surcharge. Therefore, the total charge for x hours would be

79 + 69x + 15x

= 79 + 84x
