Claire wants to buy 16 identical files as follows.
1 for $4.806 for $21.70 What is the least amount of money she needs to buy 16 such files?
Maximum number of sets that Claire can buy
= 16 ÷ 6
= 2 r 4
Amount to pay for 2 sets of 6 files
= 2 x 21.70
= $43.40
Amount to pay for the remaining files not part of a set
= 4 x 4.80
= $19.20
Least amount that Claire needed to pay
= 43.40 + 19.20
= $62.60
Answer(s): $62.60
