Emma wants to buy some pencils of the same price. If she buys 7 pencils, she will have $11.70 left. If she buys 9 pencils, she will have no money left.
- How much does each pencil cost?
- How much does Emma have?
(a)
Cost of 2 pencils = $11.70
Cost of each pencil
= 11.70 ÷ 2
= $5.85
(b)
Since Emma will have no money left if she buys 9 pencils, the amount that she has is the cost of 9 pencils.
Amount that Emma has
= 9 x 5.85
= $52.65
Answer(s): (a) $5.85; (b) $52.65
