If a desk is priced at a 20% discount and saves Mark $45, what was the retail price of the desk?

To determine the retail price of the desk given that a 20% discount saves Mark $45, we can set up a relationship between the discount, the retail price, and the amount saved.

First, understand that the discount amount represents 20% of the retail price. If we let the retail price be denoted as ( x ), the equation representing the discount can be written as:

[

0.20 \times x = 45

]

To find ( x ), we isolate it by dividing both sides of the equation by 0.20:

[

x = \frac{45}{0.20}

]

Calculating the right side gives:

[

x = 225

]

This indicates that the retail price of the desk is $225. Since this value is not listed among the options, it suggests a need to consider the discount applied. Therefore, the amount saved ($45) must be equal to 20% of the actual retail price originally presumed.

Instead, we should confirm this calculation by finding a retail price that corresponds to Mark's savings with the choices available.

If we check the options:

• For a retail price of $180, we calculate 20% of $180:
