A corporation earned a profit of $2.5 × 10^4 for 1 × 10^3 days in a row.

What was the corporation’s total profit during this time period?

To find the total profit earned by the corporation during 1 × 10^3 days, we simply 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

Total profit = Profit per day x Number of days
Total profit = ($2.5 × 10^4) x (1 × 10^3)
Total profit = $2.5 × 10^7

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