Since there are too many digits after the decimal point, we know that the answer cannot be an integer. Therefore we can eliminate choices A, D, and E. To simplify the calculation, we can use the fact that 11 × 7 = 77. After multiplying 7125 by 77, we get 548625. To adjust for the extra zeroes in the exponent of 11, we simply move the decimal point to the left 9 times, which gives us 5.48625. Finally, we can round to the nearest hundredth to get the final answer of 24592.74. Therefore, the best choice is B.
