Mason wants to buy some files of the same price. If she buys 4 files, she will have $9.20 left. If she buys 12 files, she will have no money left.
- How much does each file cost?
- How much does Mason have?
(a)
Cost of 8 files = $9.20
Cost of each file
= 9.20 ÷ 8
= $1.15
(b)
Since Mason will have no money left if she buys 12 files, the amount that she has is the cost of 12 files.
Amount that Mason has
= 12 x 1.15
= $13.80
Answer(s): (a) $1.15; (b) $13.80
