Winnie paid $24 for renting a surfboard starting from 14 00. What would be the latest time she must return the surfboard to the shop?
Amount that Winnie paid for all the additional
12 hours
= 24 - 10.50
= $13.50
Number of sets of additional
12 hours
= 13.50 ÷ 4.50
= 3
Total additional time that Winnie paid for
= 3 x
12= 1
12 h
Total time that Winnie paid for
= 1 + 1
12= 2
