Rachel wants to buy some files of the same price. If she buys 4 files, she will have $6.20 left. If she buys 6 files, she will have no money left.
- How much does each file cost?
- How much does Rachel have?
(a)
Cost of 2 files = $6.20
Cost of each file
= 6.20 ÷ 2
= $3.10
(b)
Since Rachel will have no money left if she buys 6 files, the amount that she has is the cost of 6 files.
Amount that Rachel has
= 6 x 3.10
= $18.60
Answer(s): (a) $3.10; (b) $18.60
