Question

Kim rented a bike from Kayla’s bikes. It cost $20 Plus $8 per hour. If Kim paid $52, then she rented the bike for how many hours?

Answer 1

x = the number of hours

write an equation of the problem: 8x + 20 = 52

subtract 20 from each side: 8x = 32

divide each side by 8: x = 4

she rented the bike for 4 hours.

Answer 2

$52 minus 20 which is 32 then divide 32 by 8 and you get 4. Therefore Kim rented the bike for 4 hours.
