Anna had some money. If she buys 12 lollipops, she will have $8 left. If she buys 15 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.
12 L + 8 = 15 L + 2
15 L - 12 L = 8 - 2
3 L = 6
1 L = 6 ÷ 3 = 2
Cost of each lollipop = $2
(b)
Total amount that Anna had
= 15 x 2 + 2
= 30 + 2
= $32
Answer(s): (a) $2; (b) $32
