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 so, determine how much you will owe your parents.

To determine how much you will owe your parents, we need to calculate the additional profit and then apply the 10% rule.

First, subtract $600 from the additional profit of $300 given to you by your parents:

Additional profit = $300 - $600 = -$300

Since the additional profit is negative, it means you did not make more than $600 additional profit. Therefore, you do not owe your parents any money.

In this scenario, you will owe your parents $0.

To determine how much you will owe your parents, you need to calculate the additional profit you make and subtract $600 from it. If the result is greater than $0, you would owe 10% of that amount to your parents.

Let's say the additional profit you make is x dollars.

If x - $600 > 0, then the amount you owe your parents would be 10% of (x - $600).

If you make $300 in additional profit, then x = $300.

$x - $600 = $300 - $600 = -$300

Since -$300 is less than $0, you would not owe anything to your parents.

However, if you made $800 in additional profit, then x = $800.

$x - $600 = $800 - $600 = $200

Since $200 is greater than $0, you would owe 10% of $200 to your parents.

10% of $200 = $20.

Therefore, you would owe your parents $20 if you made $800 in additional profit.

To determine how much you will owe your parents, you need to calculate the additional profit you will make after receiving the $300 and then find out if it exceeds $600.

Let's say you make an additional profit of x dollars after receiving the $300.

If x is less than or equal to $600, then you won't owe anything.

But if x is greater than $600, then you will owe 10% of the excess amount.

In this case, the excess amount is (x - $600).

So, you will owe your parents 10% of (x - $600).

Therefore, the amount you will owe your parents is:

10% of (x - $600) = 0.1(x - $600) = 0.1x - $60.
