Kyle bikes for 2 hours to work every day. Ten times the time he takes to travel to work and back is the same as the cost of buying a pack of snacks (in dollars). How much will Ryan pay, in dollars, to buy 50 packs of snacks?
Let’s work this out in a step by step way to be sure we have the right answer.
2000
A round trip to work and back takes 2 * 2 = 4 hours.

Ten times the time Kyle takes to travel to work and back is the same as the cost of buying a pack of snacks, meaning the packs are sold at 4 * 10 = $40 each.

Ryan will pay $40 * 50 = $2000 to buy 50 packs of snacks?.

The answer: 2000
