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.

Would you like further details on how this formula works or have any questions?

Here are 5 questions to expand your understanding:

1. How much would Milani earn if she washed the car for 5 weeks and waxed it once?
2. What would the equation look like if Milani earned a different amount for washing the car?
3. How would the equation change if Milani waxed the car multiple times?
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.
