Xandra paid $23.50 for renting a skateboard starting from 17 00. What would be the latest time she must return the skateboard to the shop?
Amount that Xandra paid for all the additional
12 hours
= 23.50 - 9.50
= $14
Number of sets of additional
12 hours
= 14 ÷ 3.50
= 4
Total additional time that Xandra paid for
= 4 x
12= 2 h
Total time that Xandra paid for
= 1 + 2
= 3 h
3 h after 17 00 = 20 00
Latest time that Xandra must return the skateboard to the shop: 20 00
Answer(s): 20 00
