Tonisha has a lemonade stand. She has $36 in expenses and wants to make at least $55 per day. If x represents the amount of revenue from selling lemonade, an inequality to represent the amount of revenue she would need to generate would be:

x - $36 ≥ $55

To represent the amount of revenue Tonisha would need to generate, we can set up the following inequality:

x ≥ $55

This inequality reads as "x is greater than or equal to $55." This means that the revenue from selling lemonade, represented by x, must be equal to or greater than $55 per day in order for Tonisha to meet her goal.

It's important to note that this inequality only represents the revenue she would need to generate. It does not take into account her expenses of $36 per day. To represent the profit that Tonisha would make, we would need to subtract her expenses from the revenue.

The inequality to represent the amount of revenue Tonisha would need to generate is:

x ≥ $55 + $36

This is because she wants to make at least $55 per day and she has $36 in expenses. So, the total amount of revenue she would need to generate (x) should be equal to or greater than the sum of $55 and $36.
