Grace wants to buy some files of the same price. If she buys 3 files, she will have $7.50 left. If she buys 5 files, she will have no money left.
- How much does each file cost?
- How much does Grace have?
(a)
Cost of 2 files = $7.50
Cost of each file
= 7.50 ÷ 2
= $3.75
(b)
Since Grace will have no money left if she buys 5 files, the amount that she has is the cost of 5 files.
Amount that Grace has
= 5 x 3.75
= $18.75
Answer(s): (a) $3.75; (b) $18.75
