Avery wants to buy some staplers of the same price. If she buys 3 staplers, she will have $5.20 left. If she buys 9 staplers, she will short of $1.10.
- How much does each stapler cost?
- How much does Avery have?
(a)
Difference in the number of staplers
= 9 - 3
= 6
Amount that Avery needs to buy 6 staplers
= 5.20 + 1.10
= $6.30
Cost of each stapler
= 6.30 ÷ 6
= $1.05
(b)
Amount that Avery has
= 3 x 1.05 + 5.20
= $8.35
Answer(s): (a) $1.05; (b) $8.35
