Roshel paid $27 for renting a skateboard starting from 16 00. What would be the latest time she must return the skateboard to the shop?
Amount that Roshel paid for all the additional
12 hours
= 27 - 9.50
= $17.50
Number of sets of additional
12 hours
= 17.50 ÷ 3.50
= 5
Total additional time that Roshel paid for
= 5 x
12= 2
12 h
Total time that Roshel paid for
= 1 + 2
12= 3

12 h after 16 00 = 19 30
Latest time that Roshel must return the skateboard to the shop: 19 30
