Gavin wants to buy some pencils of the same price. If she buys 5 pencils, she will have $8.80 left. If she buys 7 pencils, she will have no money left.
- How much does each pencil cost?
- How much does Gavin have?
(a)
Cost of 2 pencils = $8.80
Cost of each pencil
= 8.80 ÷ 2
= $4.40
(b)
Since Gavin will have no money left if she buys 7 pencils, the amount that she has is the cost of 7 pencils.
Amount that Gavin has
= 7 x 4.40
= $30.80
Answer(s): (a) $4.40; (b) $30.80
