Explanation

Approximate 49.99% as 50% and 21.99% as 22%. 50% of 1747 is 873.5. 22% of 1302 is approximately 0.22 * 1300 = 286. 873.5 - 286 = 587.5, which is closest to 590.

AI explanation

Using the percentage approximation method, we round the values to 50 percent of 1750 minus 22 percent of 1300. This simplifies to half of 1750, which is 875, minus 22 divided by 100 times 1300, which is 286. Subtracting 286 from 875 gives 589, making the closest approximate answer 590.
