Question

The money Mr. Jarod earns, m, varies directly with the number of haircuts he gives, h. He earns $15 for five haircuts. Which equation represents his earnings for the job?

Answer 1

m/h = k

Explanation:

Money earned = m

Number of haircuts = h

m α h

m = kh

k is the constant of proportionality

Amount earned for 5 hair cuts = 15

n = 5 ; m = 15

Earning for the job = k

From m = kh

Divide both sides by h

m / h = kh/h

m/h = k

15/5 = 3

Earning for the job = $3
