Jacob wants to buy 14 identical notebooks as follows.
1 for $4.306 for $24.80 What is the least amount of money she needs to buy 14 such notebooks?
Maximum number of sets that Jacob can buy
= 14 ÷ 6
= 2 r 2
Amount to pay for 2 sets of 6 notebooks
= 2 x 24.80
= $49.60
Amount to pay for the remaining notebooks not part of a set
= 2 x 4.30
= $8.60
Least amount that Jacob needed to pay
= 49.60 + 8.60
= $58.20
Answer(s): $58.20
