Zoe had some money. If she buys 11 lollipops, she will have $8 left. If she buys 13 lollipops, she will have $4 left.
- How much does each lollipop cost?
- How much money does she have?
(a)
Let 1 L be the price of 1 lollipop.
11 L + 8 = 13 L + 4
13 L - 11 L = 8 - 4
2 L = 4
1 L = 4 ÷ 2 = 2
Cost of each lollipop = $2
(b)
Total amount that Zoe had
= 13 x 2 + 4
= 26 + 4
= $30
Answer(s): (a) $2; (b) $30
