Kaylee wants to buy some pens of the same price. If she buys 7 pens, she will have $7.60 left. If she buys 11 pens, she will have no money left.
- How much does each pen cost?
- How much does Kaylee have?
(a)
Cost of 4 pens = $7.60
Cost of each pen
= 7.60 ÷ 4
= $1.90
(b)
Since Kaylee will have no money left if she buys 11 pens, the amount that she has is the cost of 11 pens.
Amount that Kaylee has
= 11 x 1.90
= $20.90
Answer(s): (a) $1.90; (b) $20.90
