Emma wants to buy 19 identical staplers as follows.
1 for $4.706 for $24.20 What is the least amount of money she needs to buy 19 such staplers?
Maximum number of sets that Emma can buy
= 19 ÷ 6
= 3 r 1
Amount to pay for 3 sets of 6 staplers
= 3 x 24.20
= $72.60
Amount to pay for the remaining staplers not part of a set
= 1 x 4.70
= $4.70
Least amount that Emma needed to pay
= 72.60 + 4.70
= $77.30
Answer(s): $77.30
