Gavin wants to buy some markers of the same price. If she buys 2 markers, she will have $3.70 left. If she buys 8 markers, she will short of $1.40.
- How much does each marker cost?
- How much does Gavin have?
(a)
Difference in the number of markers
= 8 - 2
= 6
Amount that Gavin needs to buy 6 markers
= 3.70 + 1.40
= $5.10
Cost of each marker
= 5.10 ÷ 6
= $0.85
(b)
Amount that Gavin has
= 2 x 0.85 + 3.70
= $5.40
Answer(s): (a) $0.85; (b) $5.40
