Anastasia uses the equation p=0.7 (rh+b) to estimate the amount of take-home pay, p, for h hours worked at a rate of r dollars per hour and any bonus recived, b.

This problem is incomplete. But I have encountered this problem before. It was looking for the formula of h, hours worked.

Given:

p = take home pay

r = rate of dollars per hour

h = number of hours worked

b = bonus

Find h:

p = 0.7 (rh + b)

p = 0.7*r*h + 0.7b

p - 0.7b = 0.7rh

(p-0.7b) / 0.7r = h
