Marion had some money. If she buys 7 lollipops, she will have $5 left. If she buys 9 lollipops, she will have $1 left.
- How much does each lollipop cost?
- How much money does she have?
(a)
Let 1 L be the price of 1 lollipop.
7 L + 5 = 9 L + 1
9 L - 7 L = 5 - 1
2 L = 4
1 L = 4 ÷ 2 = 2
Cost of each lollipop = $2
(b)
Total amount that Marion had
= 9 x 2 + 1
= 18 + 1
= $19
Answer(s): (a) $2; (b) $19
