Nora paid $25 for renting a snowboard starting from 17 00. What would be the latest time she must return the snowboard to the shop?
Amount that Nora paid for all the additional
12 hours
= 25 - 11.50
= $13.50
Number of sets of additional
12 hours
= 13.50 ÷ 4.50
= 3
Total additional time that Nora paid for
= 3 x
12= 1
12 h
Total time that Nora paid for
= 1 + 1
12= 2
