The Camasta family pays $85 a month for TV

services. Next month the cost will increase by 3%

because of an equipment fee. After the cost

increase what will be the cost of their TV service?

1. Start your equation by making lines like this

- = -

2. On the top right side put x

3. On the bottom right side put 85

4. On the top left side put 3

5. On the bottom left side put 100

6. It should look like this

3 = x

- -

100 85

7. Cross multiply (100 times x equals 100x and 3 times 85 is 253)

8. Divide both by 100 (100x divided by 100 equals 1x and 253 divided by 100 is 2.53)

9. Add 2.53 to 85 (getting 87.53)

10. The answer is: The cost of their TV service is $87.53
