Nora wants to buy 16 identical markers as follows.
1 for $4.206 for $24.80 What is the least amount of money she needs to buy 16 such markers?
Maximum number of sets that Nora can buy
= 16 ÷ 6
= 2 r 4
Amount to pay for 2 sets of 6 markers
= 2 x 24.80
= $49.60
Amount to pay for the remaining markers not part of a set
= 4 x 4.20
= $16.80
Least amount that Nora needed to pay
= 49.60 + 16.80
= $66.40
Answer(s): $66.40
