Erika had some money. If she buys 10 caramel apples, she will have $8 left. If she buys 12 caramel apples, she will have $4 left.
- How much does each caramel apple cost?
- How much money does she have?
(a)
Let 1 C be the price of 1 caramel apple.
10 C + 8 = 12 C + 4
12 C - 10 C = 8 - 4
2 C = 4
1 C = 4 ÷ 2 = 2
Cost of each caramel apple = $2
(b)
Total amount that Erika had
= 12 x 2 + 4
= 24 + 4
= $28
Answer(s): (a) $2; (b) $28
