Question

John rented a bike from carlos' bikes it costs $19 plus $4 per hour if john paid $35 how many hours did he rent the bike

Answer 1

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.
