A Correct answer
Explanation

2490 / 10 = 249. 55% of 270 = 0.55 * 270 = 148.5. 249 + 148.5 = 397.5, which is approximately 400.

AI explanation

Using the approximation method, we round the numbers to 2500 divided by 10 plus 55 percent of 270. The first term becomes 250 and the second term is calculated as 0.55 times 270, which equals 148.5. Adding these two values gives 250 plus 148.5, resulting in a total of 398.5. Therefore, the closest approximate value is 400.
