Aubrey wants to buy some pens of the same price. If she buys 8 pens, she will have $11.20 left. If she buys 12 pens, she will have no money left.
- How much does each pen cost?
- How much does Aubrey have?
(a)
Cost of 4 pens = $11.20
Cost of each pen
= 11.20 ÷ 4
= $2.80
(b)
Since Aubrey will have no money left if she buys 12 pens, the amount that she has is the cost of 12 pens.
Amount that Aubrey has
= 12 x 2.80
= $33.60
Answer(s): (a) $2.80; (b) $33.60
