Dana had some money. If she buys 10 lollipops, she will have $6 left. If she buys 12 lollipops, she will have $2 left.
- How much does each lollipop cost?
- How much money does she have?
(a)
Let 1 L be the price of 1 lollipop.
10 L + 6 = 12 L + 2
12 L - 10 L = 6 - 2
2 L = 4
1 L = 4 ÷ 2 = 2
Cost of each lollipop = $2
(b)
Total amount that Dana had
= 12 x 2 + 2
= 24 + 2
= $26
Answer(s): (a) $2; (b) $26
