Riordan wants to buy some markers of the same price. If she buys 9 markers, she will have $6.50 left. If she buys 11 markers, she will have no money left.
- How much does each marker cost?
- How much does Riordan have?
(a)
Cost of 2 markers = $6.50
Cost of each marker
= 6.50 ÷ 2
= $3.25
(b)
Since Riordan will have no money left if she buys 11 markers, the amount that she has is the cost of 11 markers.
Amount that Riordan has
= 11 x 3.25
= $35.75
Answer(s): (a) $3.25; (b) $35.75
