Stella wants to buy some markers of the same price. If she buys 5 markers, she will have $6.60 left. If she buys 8 markers, she will short of $1.20.
- How much does each marker cost?
- How much does Stella have?
(a)
Difference in the number of markers
= 8 - 5
= 3
Amount that Stella needs to buy 3 markers
= 6.60 + 1.20
= $7.80
Cost of each marker
= 7.80 ÷ 3
= $2.60
(b)
Amount that Stella has
= 5 x 2.60 + 6.60
= $19.60
Answer(s): (a) $2.60; (b) $19.60
