She has 200
80 deposit - 200= 120 left to spend
80+30h=200
If she has 120 left to spend at 30 hr, she could have the boat for 4 hrs
80+30h=200 subtract 80 from both sides
30h=120 divide by the 30
h=4
Unit cost to sales price is 1:4.....or 1/4
1 / 4 = 33.85 / s.....1 unit cost to 4 sales price = 33.85 unit cost = s sales price
cross multiply
(1)(s) = (4)(33.85)
s = 135.40 <=== selling price
