Jeremiah wants to buy some markers of the same price. If she buys 3 markers, she will have $8.80 left. If she buys 7 markers, she will have no money left.
- How much does each marker cost?
- How much does Jeremiah have?
(a)
Cost of 4 markers = $8.80
Cost of each marker
= 8.80 ÷ 4
= $2.20
(b)
Since Jeremiah will have no money left if she buys 7 markers, the amount that she has is the cost of 7 markers.
Amount that Jeremiah has
= 7 x 2.20
= $15.40
Answer(s): (a) $2.20; (b) $15.40
