Evan wants to buy some staplers of the same price. If she buys 4 staplers, she will have $5.10 left. If she buys 6 staplers, she will short of $1.90.
- 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
= 5.10 + 1.90
= $7.00
Cost of each stapler
= 7.00 ÷ 2
= $3.50
(b)
Amount that Evan has
= 4 x 3.50 + 5.10
= $19.10
Answer(s): (a) $3.50; (b) $19.10
