Alexander wants to buy some markers of the same price. If she buys 2 markers, she will have $7.30 left. If she buys 6 markers, she will short of $2.30.
- How much does each marker cost?
- How much does Alexander have?
(a)
Difference in the number of markers
= 6 - 2
= 4
Amount that Alexander needs to buy 4 markers
= 7.30 + 2.30
= $9.60
Cost of each marker
= 9.60 ÷ 4
= $2.40
(b)
Amount that Alexander has

= $12.10
Answer(s): (a) $2.40; (b) $12.10
