Ethan wants to buy some notebooks of the same price. If she buys 5 notebooks, she will have $6.60 left. If she buys 9 notebooks, she will have no money left.
- How much does each notebook cost?
- How much does Ethan have?
(a)
Cost of 4 notebooks = $6.60
Cost of each notebook
= 6.60 ÷ 4
= $1.65
(b)
Since Ethan will have no money left if she buys 9 notebooks, the amount that she has is the cost of 9 notebooks.
Amount that Ethan has
= 9 x 1.65
= $14.85
Answer(s): (a) $1.65; (b) $14.85
