Let's break down the calculation step by step:

- 17.77% of 399.99: Approximately 17.77% of 400 is 71.08.

- 42.14% of 249.99: Approximately 42.14% of 250 is 105.35.

- Add these: 71.08 + 105.35 = 176.43.

- 15.99% of 199.98: Approximately 15.99% of 200 is 31.98.

Now solve for '?':

- Formula: 176.43 = ? – 31.98

- Add 31.98 to both sides: 176.43 + 31.98 = ?, which equals 208.41.

Rounding 208.41 gives us approximately 209.
