Amelia wants to buy 16 identical markers as follows.
1 for $4.405 for $20.90 What is the least amount of money she needs to buy 16 such markers?
Maximum number of sets that Amelia can buy
= 16 ÷ 5
= 3 r 1
Amount to pay for 3 sets of 5 markers
= 3 x 20.90
= $62.70
Amount to pay for the remaining markers not part of a set
= 1 x 4.40
= $4.40
Least amount that Amelia needed to pay
= 62.70 + 4.40
= $67.10
Answer(s): $67.10
