# Summary of the Math: Proportional Relationships and Percent

Write a summary about solving sales tax problems and how proportional relationships and percent are connected.

## Hint:

Check your summary.

- Do you explain how to find the total cost when there is sales tax?
- Do you point out that the sales tax must be constant in order for a proportional relationship to exist between the price of each item and the total cost of the item?
- Do you explain how percent is connected to the constant of proportionality?
