Samuel wants to buy some markers of the same price. If she buys 5 markers, she will have $3.60 left. If she buys 7 markers, she will short of $1.50.
- How much does each marker cost?
- How much does Samuel have?
(a)
Difference in the number of markers
= 7 - 5
= 2
Amount that Samuel needs to buy 2 markers
= 3.60 + 1.50
= $5.10
Cost of each marker
= 5.10 ÷ 2
= $2.55
(b)
Amount that Samuel has
= 5 x 2.55 + 3.60
= $16.35
Answer(s): (a) $2.55; (b) $16.35
