Xuan paid $25 for renting a skateboard starting from 15 00. What would be the latest time she must return the skateboard to the shop?
Amount that Xuan paid for all the additional
12 hours
= 25 - 7.50
= $17.50
Number of sets of additional
12 hours
= 17.50 ÷ 3.50
= 5
Total additional time that Xuan paid for
= 5 x
12= 2
12 h
Total time that Xuan paid for
= 1 + 2
12= 3

12 h after 15 00 = 18 30
Latest time that Xuan must return the skateboard to the shop: 18 30
