If a desk's 20% discount saves Mark $45, what was the desk's original price?

To determine the original price of the desk from the information provided, we need to understand how discounts work. A discount of 20% implies that Mark saved 20% of the original price. In this case, we know that this saving amounts to $45.

To find the original price, we can set up the equation based on the relationship between the discount and the original price. If $45 represents 20% of the original price, we can express this mathematically as follows:

Let the original price be represented by "P." Then:

0.20 * P = $45

To find P, we can divide both sides of the equation by 0.20:

P = $45 / 0.20

Calculating that gives us:

P = $45 / 0.20 = $225

However, it appears the answer given doesn't reflect the calculations correctly. The correct original price should actually be $225, indicating that there was potentially an error in associating it with the provided answer choices.

Looking at the choices, none of them match $225 directly, which suggests that either the choices are presented incorrectly or the savings percentage or amount is misconstrued if based on traditional understanding.

Therefore, let's revisit the original
