and additionally pays 15 per cent of revenue back to the salon. Suppose that the hair
stylist's average revenue is 120 dollars per client.

revenue per client.)

Let us assume that the hair stylist works on X clients in a week.
Then weekly income = 120X

Weekly Cost, C = weekly rent of chair + 15% of weekly income
C = 500 + 0.15(120X)
C = 500 + 18X

Weekly Revenue , R = Weekly income - weekly cost
R = 120X - (500 + 18X)
R = 102X - 500

1.)
Assume there are x clients in that week. It then follows that the weekly cost function can be written as:
C = 500 + 0.15(120x) = 500 + 18x

2.)
Weekly Revenue = R = 120x
