Gwen paid $23 for renting a snowboard starting from 17 00. What would be the latest time she must return the snowboard to the shop?
Amount that Gwen paid for all the additional
12 hours
= 23 - 5.50
= $17.50
Number of sets of additional
12 hours
= 17.50 ÷ 2.50
= 7
Total additional time that Gwen paid for
= 7 x
12= 3
12 h
Total time that Gwen paid for
= 1 + 3
12= 4
12 h
4
12 h after 17 00 = 21 30
Latest time that Gwen must return the snowboard to the shop: 21 30
Answer(s): 21 30
