Noah wants to buy some staplers of the same price. If she buys 4 staplers, she will have $6.50 left. If she buys 6 staplers, she will short of $1.90.
- How much does each stapler cost?
- How much does Noah have?
(a)
Difference in the number of staplers
= 6 - 4
= 2
Amount that Noah needs to buy 2 staplers
= 6.50 + 1.90
= $8.40
Cost of each stapler
= 8.40 ÷ 2
= $4.20
(b)
Amount that Noah has
= 4 x 4.20 + 6.50
= $23.30
Answer(s): (a) $4.20; (b) $23.30
