Jack wants to buy 19 identical staplers as follows.
1 for $4.206 for $20.20 What is the least amount of money she needs to buy 19 such staplers?
Maximum number of sets that Jack can buy
= 19 ÷ 6
= 3 r 1
Amount to pay for 3 sets of 6 staplers
= 3 x 20.20
= $60.60
Amount to pay for the remaining staplers not part of a set
= 1 x 4.20
= $4.20
Least amount that Jack needed to pay
= 60.60 + 4.20
= $64.80
Answer(s): $64.80
