Nora wants to buy some files of the same price. If she buys 6 files, she will have $6.40 left. If she buys 8 files, she will have no money left.
- How much does each file cost?
- How much does Nora have?
(a)
Cost of 2 files = $6.40
Cost of each file
= 6.40 ÷ 2
= $3.20
(b)
Since Nora will have no money left if she buys 8 files, the amount that she has is the cost of 8 files.
Amount that Nora has
= 8 x 3.20
= $25.60
Answer(s): (a) $3.20; (b) $25.60
