Nathan wants to buy 17 identical staplers as follows.
1 for $4.505 for $20.60 What is the least amount of money she needs to buy 17 such staplers?
Maximum number of sets that Nathan can buy
= 17 ÷ 5
= 3 r 2
Amount to pay for 3 sets of 5 staplers
= 3 x 20.60
= $61.80
Amount to pay for the remaining staplers not part of a set
= 2 x 4.50
= $9.00
Least amount that Nathan needed to pay
= 61.80 + 9.00
= $70.80
Answer(s): $70.80
