Jackson wants to buy some markers of the same price. If she buys 4 markers, she will have $6.20 left. If she buys 6 markers, she will short of $2.90.
- How much does each marker cost?
- How much does Jackson have?
(a)
Difference in the number of markers
= 6 - 4
= 2
Amount that Jackson needs to buy 2 markers
= 6.20 + 2.90
= $9.10
Cost of each marker
= 9.10 ÷ 2
= $4.55
(b)
Amount that Jackson has
= 4 x 4.55 + 6.20
= $24.40
Answer(s): (a) $4.55; (b) $24.40
