Question

A hair salon charges a fixed rate of $25.00 for a haircut and an additional $15 for any other services. Write a function to model the cost of services at the salon and then evaluate the function to determine the cost for a haircut, shampoo, highlight, and blow dry.

Answer 1

25+15•3= 70 dollars she spent on the hair salon..... dang lotsa money

Answer 2

Function : Cost =25 + 15x

Cost for a haircut, shampoo, highlight, and blow dry = $70

Explanation:

Hi, to answer this we have to write an equation:

The cost of the services will be equal to the fixed cost for the haircut (25.00) plus the product of the number of additional services (x) and the price of each additional service (15).

Mathematically speaking:

Cost =25 + 15x

To determine the cost for a haircut, shampoo, highlight, and blow dry, we have to substitute x = 3 (because shampoo, highlight, and blow dry are additional services ) in the equation and solve.

Cost = 25+ 15 (3)

Cost = 25+45

Cost = $70
