Nathan wants to buy some pencils of the same price. If she buys 10 pencils, she will have $6.80 left. If she buys 12 pencils, she will have no money left.
- How much does each pencil cost?
- How much does Nathan have?
(a)
Cost of 2 pencils = $6.80
Cost of each pencil
= 6.80 ÷ 2
= $3.40
(b)
Since Nathan will have no money left if she buys 12 pencils, the amount that she has is the cost of 12 pencils.
Amount that Nathan has
= 12 x 3.40
= $40.80
Answer(s): (a) $3.40; (b) $40.80
