Lucy paid $34 for renting a surfboard starting from 12 00. What would be the latest time she must return the surfboard to the shop?
Amount that Lucy paid for all the additional
12 hours
= 34 - 9.50
= $24.50
Number of sets of additional
12 hours
= 24.50 ÷ 3.50
= 7
Total additional time that Lucy paid for
= 7 x
12= 3
12 h
Total time that Lucy paid for
= 1 + 3
12= 4
12 h
4
12 h after 12 00 = 16 30
Latest time that Lucy must return the surfboard to the shop: 16 30
Answer(s): 16 30
