Jamie wants to buy some notebooks of the same price. If she buys 9 notebooks, she will have $11.30 left. If she buys 11 notebooks, she will have no money left.
- How much does each notebook cost?
- How much does Jamie have?
(a)
Cost of 2 notebooks = $11.30
Cost of each notebook
= 11.30 ÷ 2
= $5.65
(b)
Since Jamie will have no money left if she buys 11 notebooks, the amount that she has is the cost of 11 notebooks.
Amount that Jamie has
= 11 x 5.65
= $62.15
Answer(s): (a) $5.65; (b) $62.15
