Jane had some money. If she buys 5 caramel apples, she will have $8 left. If she buys 7 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.
5 C + 8 = 7 C + 4
7 C - 5 C = 8 - 4
2 C = 4
1 C = 4 ÷ 2 = 2
Cost of each caramel apple = $2
(b)
Total amount that Jane had
= 7 x 2 + 4
= 14 + 4
= $18
Answer(s): (a) $2; (b) $18
