A makeup artist charges $40 to travel to a wedding, plus $20 per hour for the makeup she is doing at the wedding. The bride receives a bill for $100. How many hours did the makeup artist work at the wedding? First write an equation that models the situation using function notation.

Answer 1

The makeup artist worked for 3 hours.

Explanation:

Giving the following information:

A makeup artist charges $40 to travel to a wedding, plus $20 per hour for the makeup she is doing at the wedding. The bride receives a bill for $100.

We need to structure the total cost formula:

f(x)= 40 + 20x

x= number of hours

Now, for $100:

100= 40 + 20x

60/20= x

3= x

The makeup artist worked for 3 hours.
