Marion paid $29.50 for renting a skateboard starting from 15 00. What would be the latest time she must return the skateboard to the shop?
Amount that Marion paid for all the additional
12 hours
= 29.50 - 11.50
= $18
Number of sets of additional
12 hours
= 18 ÷ 4.50
= 4
Total additional time that Marion paid for
= 4 x
12= 2 h
Total time that Marion paid for
= 1 + 2
= 3 h
3 h after 15 00 = 18 00
Latest time that Marion must return the skateboard to the shop: 18 00
Answer(s): 18 00
