Jonathan wants to buy some pens of the same price. If she buys 7 pens, she will have $10.60 left. If she buys 9 pens, she will have no money left.
- How much does each pen cost?
- How much does Jonathan have?
(a)
Cost of 2 pens = $10.60
Cost of each pen
= 10.60 ÷ 2
= $5.30
(b)
Since Jonathan will have no money left if she buys 9 pens, the amount that she has is the cost of 9 pens.
Amount that Jonathan has
= 9 x 5.30
= $47.70
Answer(s): (a) $5.30; (b) $47.70
