Avery wants to buy some pens of the same price. If she buys 9 pens, she will have $10.70 left. If she buys 11 pens, she will have no money left.
- How much does each pen cost?
- How much does Avery have?
(a)
Cost of 2 pens = $10.70
Cost of each pen
= 10.70 ÷ 2
= $5.35
(b)
Since Avery will have no money left if she buys 11 pens, the amount that she has is the cost of 11 pens.
Amount that Avery has
= 11 x 5.35
= $58.85
Answer(s): (a) $5.35; (b) $58.85
