Lucy paid $35.50 for renting a scooter starting from 15 00. What would be the latest time she must return the scooter to the shop?
Amount that Lucy paid for all the additional
12 hours
= 35.50 - 7.50
= $28
Number of sets of additional
12 hours
= 28 ÷ 3.50
= 8
Total additional time that Lucy paid for
= 8 x
12= 4 h
Total time that Lucy paid for
= 1 + 4
= 5 h
5 h after 15 00 = 20 00
Latest time that Lucy must return the scooter to the shop: 20 00
Answer(s): 20 00
