Anthony wants to buy some files of the same price. If she buys 8 files, she will have $9.90 left. If she buys 10 files, she will have no money left.
- How much does each file cost?
- How much does Anthony have?
(a)
Cost of 2 files = $9.90
Cost of each file
= 9.90 ÷ 2
= $4.95
(b)
Since Anthony will have no money left if she buys 10 files, the amount that she has is the cost of 10 files.
Amount that Anthony has
= 10 x 4.95
= $49.50
Answer(s): (a) $4.95; (b) $49.50
