Rebecca wants to buy some staplers of the same price. If she buys 3 staplers, she will have $3.80 left. If she buys 9 staplers, she will short of $1.90.
- How much does each stapler cost?
- How much does Rebecca have?
(a)
Difference in the number of staplers
= 9 - 3
= 6
Amount that Rebecca needs to buy 6 staplers
= 3.80 + 1.90
= $5.70
Cost of each stapler
= 5.70 ÷ 6
= $0.95
(b)
Amount that Rebecca has
= 3 x 0.95 + 3.80
= $6.65
Answer(s): (a) $0.95; (b) $6.65
