You can write this as an equation. P(price) = 4h(hours) +19. We know that P=35. If you plug it in, 35 = 4h +19. Subtract both sides by 19 to get 16 = 4h. Divide both sides by 4, and you get 4 = h, or the amount of hours, John rented the bike.

He paid ...

-- The cost of the lunches (100% = 1.00 of it)

-- 15% of the cost as a tip (15% = 0.15 of it)

-- 12% of the cost as sales tax (12% = 0.12 of it)
