Vanessa paid $40 for renting a snowboard starting from 15 00. What would be the latest time she must return the snowboard to the shop?
Amount that Vanessa paid for all the additional
12 hours
= 40 - 12.50
= $27.50
Number of sets of additional
12 hours
= 27.50 ÷ 5.50
= 5
Total additional time that Vanessa paid for
= 5 x
12= 2
12 h
Total time that Vanessa paid for
= 1 + 2
12= 3
