Aria wants to buy some files of the same price. If she buys 5 files, she will have $9.60 left. If she buys 11 files, she will have no money left.
- How much does each file cost?
- How much does Aria have?
(a)
Cost of 6 files = $9.60
Cost of each file
= 9.60 ÷ 6
= $1.60
(b)
Since Aria will have no money left if she buys 11 files, the amount that she has is the cost of 11 files.
Amount that Aria has
= 11 x 1.60
= $17.60
Answer(s): (a) $1.60; (b) $17.60
