Stella wants to buy 17 identical staplers as follows.
1 for $4.206 for $23.80 What is the least amount of money she needs to buy 17 such staplers?
Maximum number of sets that Stella can buy
= 17 ÷ 6
= 2 r 5
Amount to pay for 2 sets of 6 staplers
= 2 x 23.80
= $47.60
Amount to pay for the remaining staplers not part of a set
= 5 x 4.20
= $21.00
Least amount that Stella needed to pay
= 47.60 + 21.00
= $68.60
Answer(s): $68.60
