Cindy paid $29 for renting a surfboard starting from 15 00. What would be the latest time she must return the surfboard to the shop?
Amount that Cindy paid for all the additional
12 hours
= 29 - 12.50
= $16.50
Number of sets of additional
12 hours
= 16.50 ÷ 5.50
= 3
Total additional time that Cindy paid for
= 3 x
12= 1
12 h
Total time that Cindy paid for
= 1 + 1
12= 2
