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 received, b. What is an equivalent equation solved for h?

h = (h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b)÷ r
h = h equals StartFraction p Over 0.7 EndFraction minus b divided by r.– b ÷ r
h = h equals left-parenthesis StartFraction p Over 0.7 EndFraction right-parenthesis divided by r minus b.÷ r – b
h = h equals StartFraction p minus b Over 0.7 EndFraction divided by r. ÷ r
