Jen paid $32 for renting a surfboard starting from 15 00. What would be the latest time she must return the surfboard to the shop?
Amount that Jen paid for all the additional
12 hours
= 32 - 9.50
= $22.50
Number of sets of additional
12 hours
= 22.50 ÷ 4.50
= 5
Total additional time that Jen paid for
= 5 x
12= 2
12 h
Total time that Jen paid for
= 1 + 2
12= 3
