Your parents heard about the success of your business and they want to help you out. Suppose they want to give you an additional $300 to put toward your business. However, there's a catch. If you make more than $600 additional profit, you have to give them 10% of your earnings above $600. For example, if you have earned $650, then you owe 10% of $50, or $5, to your parents.

If you still sell your item for the same price, what is the most money you can hope to earn from your business now?

The most money you can hope to earn from your business now is $900.

This is calculated by adding the original profit of $600 to the additional $300 that your parents gave you.

To figure out the most money you can hope to earn from your business now, you need to determine the point at which you would start owing 10% of your earnings above $600 to your parents.

Let's say you make this additional profit as x dollars. According to the condition, when x is greater than $600, you owe 10% of (x - $600) to your parents.

So, you need to calculate the point at which x exceeds $600, and then calculate 10% of the amount above $600.

Let's set up the equation:

x - $600 > $600

Simplifying this equation, we get:

x > $1200

This means that once you earn more than $1200 in additional profit, you will owe 10% of the amount above $600 to your parents.

Now, let's calculate the most money you can hope to earn from your business by considering the condition:

When x is less than or equal to $600, you don't owe anything to your parents.

So, the most money you can hope to earn from your business is $600 (since x ≤ $600) without owing anything to your parents.

Therefore, the most money you can hope to earn from your business now is $600.

To determine the most money you can hope to earn from your business now, we need to consider the additional $300 from your parents and the condition that you have to give them 10% of your earnings above $600.

First, let's calculate the earnings above $600. Since you are given an additional $300, your total earnings above $600 will be $300.

Next, let's calculate the amount you have to give your parents. Since they require 10% of your earnings above $600, you will owe them 10% of $300, which is $30.

Now, subtract the amount you owe your parents from your additional earnings to calculate your net additional profit. So, $300 - $30 = $270.

Therefore, the most money you can hope to earn from your business now is an additional $270.
