Harris wants to buy some staplers of the same price. If she buys 6 staplers, she will have $7.80 left. If she buys 9 staplers, she will have no money left.
- How much does each stapler cost?
- How much does Harris have?
(a)
Cost of 3 staplers = $7.80
Cost of each stapler
= 7.80 ÷ 3
= $2.60
(b)
Since Harris will have no money left if she buys 9 staplers, the amount that she has is the cost of 9 staplers.
Amount that Harris has
= 9 x 2.60
= $23.40
Answer(s): (a) $2.60; (b) $23.40
