Marion paid $10 for renting a scooter starting from 16 00. What would be the latest time she must return the scooter to the shop?
Amount that Marion paid for all the additional
12 hours
= 10 - 5.50
= $4.50
Number of sets of additional
12 hours
= 4.50 ÷ 1.50
= 3
Total additional time that Marion paid for
= 3 x
12= 1
12 h
Total time that Marion paid for
= 1 + 1
12= 2

12 h after 16 00 = 18 30
Latest time that Marion must return the scooter to the shop: 18 30
