Lilian wants to buy some staplers of the same price. If she buys 2 staplers, she will have $7.40 left. If she buys 4 staplers, she will short of $1.80.
- How much does each stapler cost?
- How much does Lilian have?
(a)
Difference in the number of staplers
= 4 - 2
= 2
Amount that Lilian needs to buy 2 staplers
= 7.40 + 1.80
= $9.20
Cost of each stapler
= 9.20 ÷ 2
= $4.60
(b)
Amount that Lilian has
= 2 x 4.60 + 7.40
= $16.60
Answer(s): (a) $4.60; (b) $16.60
