Anthony wants to buy some pens of the same price. If she buys 8 pens, she will have $9.70 left. If she buys 10 pens, she will have no money left.
- How much does each pen cost?
- How much does Anthony have?
(a)
Cost of 2 pens = $9.70
Cost of each pen
= 9.70 ÷ 2
= $4.85
(b)
Since Anthony will have no money left if she buys 10 pens, the amount that she has is the cost of 10 pens.
Amount that Anthony has
= 10 x 4.85
= $48.50
Answer(s): (a) $4.85; (b) $48.50
