Emily wants to buy 19 identical markers as follows.
1 for $4.705 for $21.50 What is the least amount of money she needs to buy 19 such markers?
Maximum number of sets that Emily can buy
= 19 ÷ 5
= 3 r 4
Amount to pay for 3 sets of 5 markers
= 3 x 21.50
= $64.50
Amount to pay for the remaining markers not part of a set
= 4 x 4.70
= $18.80
Least amount that Emily needed to pay
= 64.50 + 18.80
= $83.30
Answer(s): $83.30
