Sebastian wants to buy some files of the same price. If she buys 3 files, she will have $11.20 left. If she buys 11 files, she will have no money left.
- How much does each file cost?
- How much does Sebastian have?
(a)
Cost of 8 files = $11.20
Cost of each file
= 11.20 ÷ 8
= $1.40
(b)
Since Sebastian will have no money left if she buys 11 files, the amount that she has is the cost of 11 files.
Amount that Sebastian has
= 11 x 1.40
= $15.40
Answer(s): (a) $1.40; (b) $15.40
