Jacob wants to buy 16 identical markers as follows.
1 for $4.106 for $20.20 What is the least amount of money she needs to buy 16 such markers?
Maximum number of sets that Jacob can buy
= 16 ÷ 6
= 2 r 4
Amount to pay for 2 sets of 6 markers
= 2 x 20.20
= $40.40
Amount to pay for the remaining markers not part of a set
= 4 x 4.10
= $16.40
Least amount that Jacob needed to pay
= 40.40 + 16.40
= $56.80
Answer(s): $56.80
