Julie paid $42 for renting a snowboard starting from 14 00. What would be the latest time she must return the snowboard to the shop?
Amount that Julie paid for all the additional
12 hours
= 42 - 10.50
= $31.50
Number of sets of additional
12 hours
= 31.50 ÷ 4.50
= 7
Total additional time that Julie paid for
= 7 x
12= 3
12 h
Total time that Julie paid for
= 1 + 3
12= 4
12 h

12 h after 14 00 = 18 30
Latest time that Julie must return the snowboard to the shop: 18 30
