Anna paid $23.50 for renting a snowboard starting from 14 00. What would be the latest time she must return the snowboard to the shop?
Amount that Anna paid for all the additional
12 hours
= 23.50 - 9.50
= $14
Number of sets of additional
12 hours
= 14 ÷ 3.50
= 4
Total additional time that Anna paid for
= 4 x
12= 2 h
Total time that Anna paid for
= 1 + 2
= 3 h
3 h after 14 00 = 17 00
Latest time that Anna must return the snowboard to the shop: 17 00
Answer(s): 17 00
