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 make up artist work at the wedding? First write an equation that models this situation using function notation, then solve. (1 point)

Let's assume that the makeup artist worked for "x" number of hours at the wedding.

The equation that models this situation using function notation would be:
f(x) = $40 (travel cost) + $20 (hourly rate) * x (number of hours worked)

Given that the bride received a bill for $100, we can now write the equation as:
100 = 40 + 20x

Subtracting 40 from both sides of the equation, we have:
60 = 20x

Now, divide both sides of the equation by 20:
x = 3

Therefore, the makeup artist worked for 3 hours at the wedding.
