Charlotte wants to buy 13 identical markers as follows.
1 for $4.806 for $24.80 What is the least amount of money she needs to buy 13 such markers?
Maximum number of sets that Charlotte can buy
= 13 ÷ 6
= 2 r 1
Amount to pay for 2 sets of 6 markers
= 2 x 24.80
= $49.60
Amount to pay for the remaining markers not part of a set
= 1 x 4.80
= $4.80
Least amount that Charlotte needed to pay
= 49.60 + 4.80
= $54.40
Answer(s): $54.40
