Evan wants to buy some staplers of the same price. If she buys 4 staplers, she will have $4.90 left. If she buys 6 staplers, she will short of $2.50.
- How much does each stapler cost?
- How much does Evan have?
(a)
Difference in the number of staplers
= 6 - 4
= 2
Amount that Evan needs to buy 2 staplers
= 4.90 + 2.50
= $7.40
Cost of each stapler
= 7.40 ÷ 2
= $3.70
(b)
Amount that Evan has
= 4 x 3.70 + 4.90
= $19.70
Answer(s): (a) $3.70; (b) $19.70
