Luke wants to buy some staplers of the same price. If she buys 2 staplers, she will have $4.70 left. If she buys 6 staplers, she will short of $1.70.
- How much does each stapler cost?
- How much does Luke have?
(a)
Difference in the number of staplers
= 6 - 2
= 4
Amount that Luke needs to buy 4 staplers
= 4.70 + 1.70
= $6.40
Cost of each stapler
= 6.40 ÷ 4
= $1.60
(b)
Amount that Luke has
= 2 x 1.60 + 4.70
= $7.90
Answer(s): (a) $1.60; (b) $7.90
