The ratio of Kelly's money to Vera’s money was 7:3. After Kelly spent $35, she had $9 more than Vera. How much money did each girl have at first?

Answer 1

Use the ratio 7 to 3 to represent Kelly's money and Vera's money.

Let 7x represent Kelly's money.

Let 3x represent Vera's money.

If Kelly spends $35 dollars, then she has 7x - 35.

7x - 35 = 3x +9

After solving for x, use 7x and 3x to determine how much money each girl had at first.
