To find the corporation's total profit during this time period, we need to multiply the profit per day by the number of days.

Profit per day = $2.5 × 10^4
Number of days = 1 × 10^3

To multiply these two values, we add the exponents together.

(2.5 × 10^4) * (1 × 10^3) = 2.5 × 1 × 10^(4 + 3) = 2.5 × 10^7

Therefore, the corporation's total profit during this time period is $2.5 × 10^7.

The correct answer is B. 2.5 X 10^7

To write 1,336,000,000 in scientific notation, we need to move the decimal point to the right so that only one digit is left in front of the decimal.

1,336,000,000 = 1.336 x 10^9

Therefore, the correct scientific notation form of the number is 1.336 x 10^9.

The correct answer is B. 1.336 x 10^9.
