Ellie wants to buy some staplers of the same price. If she buys 9 staplers, she will have $9.90 left. If she buys 11 staplers, she will have no money left.
- How much does each stapler cost?
- How much does Ellie have?
(a)
Cost of 2 staplers = $9.90
Cost of each stapler
= 9.90 ÷ 2
= $4.95
(b)
Since Ellie will have no money left if she buys 11 staplers, the amount that she has is the cost of 11 staplers.
Amount that Ellie has
= 11 x 4.95
= $54.45
Answer(s): (a) $4.95; (b) $54.45
