Lilian wants to buy some staplers of the same price. If she buys 3 staplers, she will have $6.60 left. If she buys 5 staplers, she will short of $2.50.
- How much does each stapler cost?
- How much does Lilian have?
(a)
Difference in the number of staplers
= 5 - 3
= 2
Amount that Lilian needs to buy 2 staplers
= 6.60 + 2.50
= $9.10
Cost of each stapler
= 9.10 ÷ 2
= $4.55
(b)
Amount that Lilian has
= 3 x 4.55 + 6.60
= $20.25
Answer(s): (a) $4.55; (b) $20.25
