Kathy had some money. If she buys 7 caramel apples, she will have $10 left. If she buys 10 caramel apples, she will have $1 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.
7 C + 10 = 10 C + 1
10 C - 7 C = 10 - 1
3 C = 9
1 C = 9 ÷ 3 = 3
Cost of each caramel apple = $3
(b)
Total amount that Kathy had
= 10 x 3 + 1
= 30 + 1
= $31
Answer(s): (a) $3; (b) $31
