Christian wants to buy some staplers of the same price. If she buys 2 staplers, she will have $5.50 left. If she buys 8 staplers, she will short of $1.70.
- How much does each stapler cost?
- How much does Christian have?
(a)
Difference in the number of staplers
= 8 - 2
= 6
Amount that Christian needs to buy 6 staplers

= $7.20
Cost of each stapler
= 7.20 ÷ 6
= $1.20
(b)
Amount that Christian has
= 2 x 1.20 + 5.50
= $7.90
Answer(s): (a) $1.20; (b) $7.90
