Kylie paid $19 for renting a snowboard starting from 16 00. What would be the latest time she must return the snowboard to the shop?
Amount that Kylie paid for all the additional
12 hours
= 19 - 8.50
= $10.50
Number of sets of additional
12 hours
= 10.50 ÷ 3.50
= 3
Total additional time that Kylie paid for
= 3 x
12= 1
12 h
Total time that Kylie paid for
= 1 + 1
12= 2
