The problem asks to write an equation that represents Ivanna's total pay, denoted as $p$, after working $h$ hours, given that she makes 9 dollars for each hour of work.

The total pay $p$ can be calculated by multiplying the number of hours worked $h$ by her hourly wage, which is 9 dollars.

Thus, the equation to represent her total pay is:

$p = 9h$

This equation means that for every hour $h$ Ivanna works, her total pay $p$ increases by 9 dollars.

Would you like further clarification, or do you have any questions?

Here are 5 related questions:

1. How would the equation change if Ivanna made $12 per hour instead of $9?
2. What would be her total pay after working 5 hours?
3. If Ivanna wanted to make $90, how many hours would she need to work?
4. What is the relationship between the number of hours worked and the total pay?
5. How would you graph this equation on a coordinate plane?

Tip: Always ensure units are consistent in an equation. In this case, dollars per hour matches hours worked!
