Isaiah wants to buy some pencils of the same price. If she buys 8 pencils, she will have $6.60 left. If she buys 12 pencils, she will have no money left.
- How much does each pencil cost?
- How much does Isaiah have?
(a)
Cost of 4 pencils = $6.60
Cost of each pencil
= 6.60 ÷ 4
= $1.65
(b)
Since Isaiah will have no money left if she buys 12 pencils, the amount that she has is the cost of 12 pencils.
Amount that Isaiah has
= 12 x 1.65
= $19.80
Answer(s): (a) $1.65; (b) $19.80
