Julian wants to buy some staplers of the same price. If she buys 2 staplers, she will have $3.20 left. If she buys 4 staplers, she will short of $2.50.
- How much does each stapler cost?
- How much does Julian have?
(a)
Difference in the number of staplers
= 4 - 2
= 2
Amount that Julian needs to buy 2 staplers
= 3.20 + 2.50
= $5.70
Cost of each stapler
= 5.70 ÷ 2
= $2.85
(b)
Amount that Julian has
= 2 x 2.85 + 3.20
= $8.90
Answer(s): (a) $2.85; (b) $8.90
