Julian wants to buy 19 identical files as follows.
1 for $4.806 for $24.70 What is the least amount of money she needs to buy 19 such files?
Maximum number of sets that Julian can buy
= 19 ÷ 6
= 3 r 1
Amount to pay for 3 sets of 6 files
= 3 x 24.70
= $74.10
Amount to pay for the remaining files not part of a set
= 1 x 4.80
= $4.80
Least amount that Julian needed to pay
= 74.10 + 4.80
= $78.90
Answer(s): $78.90
