Jonathan wants to buy some pens of the same price. If she buys 6 pens, she will have $11.70 left. If she buys 12 pens, she will have no money left.
- How much does each pen cost?
- How much does Jonathan have?
(a)
Cost of 6 pens = $11.70
Cost of each pen
= 11.70 ÷ 6
= $1.95
(b)
Since Jonathan will have no money left if she buys 12 pens, the amount that she has is the cost of 12 pens.
Amount that Jonathan has
= 12 x 1.95
= $23.40
Answer(s): (a) $1.95; (b) $23.40
