Owen wants to buy some files of the same price. If she buys 4 files, she will have $5.60 left. If she buys 6 files, she will short of $1.90.
- How much does each file cost?
- How much does Owen have?
(a)
Difference in the number of files
= 6 - 4
= 2
Amount that Owen needs to buy 2 files
= 5.60 + 1.90
= $7.50
Cost of each file
= 7.50 ÷ 2
= $3.75
(b)
Amount that Owen has
= 4 x 3.75 + 5.60
= $20.60
Answer(s): (a) $3.75; (b) $20.60
