Riordan wants to buy some markers of the same price. If she buys 5 markers, she will have $10.60 left. If she buys 7 markers, she will have no money left.
- How much does each marker cost?
- How much does Riordan have?
(a)
Cost of 2 markers = $10.60
Cost of each marker
= 10.60 ÷ 2
= $5.30
(b)
Since Riordan will have no money left if she buys 7 markers, the amount that she has is the cost of 7 markers.
Amount that Riordan has
= 7 x 5.30
= $37.10
Answer(s): (a) $5.30; (b) $37.10
