David wants to buy some staplers of the same price. If she buys 10 staplers, she will have $10.80 left. If she buys 12 staplers, she will have no money left.
- How much does each stapler cost?
- How much does David have?
(a)
Cost of 2 staplers = $10.80
Cost of each stapler
= 10.80 ÷ 2
= $5.40
(b)
Since David will have no money left if she buys 12 staplers, the amount that she has is the cost of 12 staplers.
Amount that David has
= 12 x 5.40
= $64.80
Answer(s): (a) $5.40; (b) $64.80
