Milani earns $___ each time she washes the car. She washes her family's car each week. She also earned an additional $___ for waxing the car one week.

Part A: Rewrite the description by filling in the blanks with values of your choice to show the amount of money she could earn in any number of weeks, w. Make sure that the values you choose make sense for this situation.

Let's choose the values for the blanks in a way that makes sense for this scenario. We'll say Milani earns $15 each time she washes the car, and she earned an additional $10 for waxing the car one week.

So, the rewritten description would be:

Milani earns **$15** each time she washes the car. She washes her family's car each week. She also earned an additional **$10** for waxing the car one week.

To express the total amount of money Milani could earn in any number of weeks, **w**, we can break it down as follows:
- She earns $15 each week for washing the car, so in **w** weeks, she would earn $ 15w $.
- She earned an extra $10 in one of those weeks for waxing the car.

The total amount of money Milani earns in **w** weeks would be:
\[
\text{Total earnings} = 15w + 10
\]

This equation shows her earnings over any number of weeks **w**, including the one-time bonus for waxing.

4. Can you rewrite the equation if she earns a one-time bonus of $20 for waxing instead?
5. What happens to her total earnings if she skips waxing the car?

**Tip**: Always make sure to distinguish between weekly earnings and one-time bonuses in equations.
