Yen paid $8 for renting a paddle boat starting from 17 00. What would be the latest time she must return the paddle boat to the shop?
Amount that Yen paid for all the additional
12 hours
= 8 - 3.50
= $4.50
Number of sets of additional
12 hours
= 4.50 ÷ 1.50
= 3
Total additional time that Yen paid for
= 3 x
12= 1
12 h
Total time that Yen paid for
= 1 + 1
12= 2

12 h after 17 00 = 19 30
Latest time that Yen must return the paddle boat to the shop: 19 30
