Jacob wants to buy some markers of the same price. If she buys 3 markers, she will have $4.20 left. If she buys 5 markers, she will short of $1.20.
- How much does each marker cost?
- How much does Jacob have?
(a)
Difference in the number of markers
= 5 - 3
= 2
Amount that Jacob needs to buy 2 markers
= 4.20 + 1.20
= $5.40
Cost of each marker
= 5.40 ÷ 2
= $2.70
(b)
Amount that Jacob has
= 3 x 2.70 + 4.20
= $12.30
Answer(s): (a) $2.70; (b) $12.30
