C Correct answer
Explanation

Calculate the terms: 5% of 90 is 4.5, 20% of 149 is 29.8, and 79% of 498 is approximately 0.8 * 500 = 400. Then 4.5 + 29.8 - 393.42 = -359.12, which is closest to -365.

AI explanation

Approximate the terms to 20 percent of 150 minus 79 percent of 500, calculating 5 percent of 90 as a negligible 4.5. This simplifies the expression to 30 minus 395. Subtracting 395 from 30 gives negative 365.
