Elijah wants to buy 15 identical files as follows.
1 for $4.806 for $25.90 What is the least amount of money she needs to buy 15 such files?
Maximum number of sets that Elijah can buy
= 15 ÷ 6
= 2 r 3
Amount to pay for 2 sets of 6 files
= 2 x 25.90
= $51.80
Amount to pay for the remaining files not part of a set
= 3 x 4.80
= $14.40
Least amount that Elijah needed to pay
= 51.80 + 14.40
= $66.20
Answer(s): $66.20
