Pamela had some money. If she buys 9 lollipops, she will have $10 left. If she buys 12 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.
9 L + 10 = 12 L + 1
12 L - 9 L = 10 - 1
3 L = 9
1 L = 9 ÷ 3 = 3
Cost of each lollipop = $3
(b)
Total amount that Pamela had
= 12 x 3 + 1
= 36 + 1
= $37
Answer(s): (a) $3; (b) $37
