What is the total interior design fee after including the coordination fee?

• A. $189,750
• B. $172,500
• C. $196,500
• D. $210,000

Answer: (A)

The total is found by adding the coordination fee to the interior design fee, with the coordination fee usually a percentage of the interior design fee.

If the interior design fee is 172,500 and the coordination fee is 10% of that, the coordination amount is 17,250. Adding them gives 172,500 + 17,250 = 189,750.

So the total interior design fee after including the coordination fee is 189,750. If the coordination percentage changes, apply the same method: calculate the coordination amount as that percentage of the base fee, then add it to the base.
