Julie had some money. If she buys 4 lollipops, she will have $9 left. If she buys 6 lollipops, she will have $3 left.
- How much does each lollipop cost?
- How much money does she have?
(a)
Let 1 L be the price of 1 lollipop.
4 L + 9 = 6 L + 3
6 L - 4 L = 9 - 3
2 L = 6
1 L = 6 ÷ 2 = 3
Cost of each lollipop = $3
(b)
Total amount that Julie had
= 6 x 3 + 3
= 18 + 3
= $21
Answer(s): (a) $3; (b) $21
