Cindy paid $15.50 for renting a skateboard starting from 17 00. What would be the latest time she must return the skateboard to the shop?
Amount that Cindy paid for all the additional
12 hours
= 15.50 - 3.50
= $12
Number of sets of additional
12 hours
= 12 ÷ 1.50
= 8
Total additional time that Cindy paid for
= 8 x
12= 4 h
Total time that Cindy paid for
= 1 + 4
= 5 h
5 h after 17 00 = 22 00
Latest time that Cindy must return the skateboard to the shop: 22 00
Answer(s): 22 00
