Josiah wants to buy some files of the same price. If she buys 6 files, she will have $9.90 left. If she buys 9 files, she will have no money left.
- How much does each file cost?
- How much does Josiah have?
(a)
Cost of 3 files = $9.90
Cost of each file
= 9.90 ÷ 3
= $3.30
(b)
Since Josiah will have no money left if she buys 9 files, the amount that she has is the cost of 9 files.
Amount that Josiah has
= 9 x 3.30
= $29.70
Answer(s): (a) $3.30; (b) $29.70
