Aubrey wants to buy 17 identical markers as follows.
1 for $4.106 for $21.80 What is the least amount of money she needs to buy 17 such markers?
Maximum number of sets that Aubrey can buy
= 17 ÷ 6
= 2 r 5
Amount to pay for 2 sets of 6 markers
= 2 x 21.80
= $43.60
Amount to pay for the remaining markers not part of a set
= 5 x 4.10
= $20.50
Least amount that Aubrey needed to pay
= 43.60 + 20.50
= $64.10
Answer(s): $64.10
