Joseph wants to buy 16 identical pencils as follows.
1 for $4.706 for $21.70 What is the least amount of money she needs to buy 16 such pencils?
Maximum number of sets that Joseph can buy
= 16 ÷ 6
= 2 r 4
Amount to pay for 2 sets of 6 pencils
= 2 x 21.70
= $43.40
Amount to pay for the remaining pencils not part of a set
= 4 x 4.70
= $18.80
Least amount that Joseph needed to pay
= 43.40 + 18.80
= $62.20
Answer(s): $62.20
