Christian wants to buy some staplers of the same price. If she buys 5 staplers, she will have $6.80 left. If she buys 7 staplers, she will have no money left.
- How much does each stapler cost?
- How much does Christian have?
(a)
Cost of 2 staplers = $6.80
Cost of each stapler
= 6.80 ÷ 2
= $3.40
(b)
Since Christian will have no money left if she buys 7 staplers, the amount that she has is the cost of 7 staplers.
Amount that Christian has
= 7 x 3.40
= $23.80
Answer(s): (a) $3.40; (b) $23.80
