Barbara had some money. If she buys 7 candy canes, she will have $10 left. If she buys 9 candy canes, she will have $2 left.
- How much does each candy cane cost?
- How much money does she have?
(a)
Let 1 C be the price of 1 candy cane.
7 C + 10 = 9 C + 2
9 C - 7 C = 10 - 2
2 C = 8
1 C = 8 ÷ 2 = 4
Cost of each candy cane = $4
(b)
Total amount that Barbara had
= 9 x 4 + 2
= 36 + 2
= $38
Answer(s): (a) $4; (b) $38
