A corporation earned a profit of $2.5 × 104 for 1 × 103 days in a row. What was the corporation’s total profit during this time period? Write the answer in scientific notation.
To find the total profit during the 1 × 103 days, we can multiply the profit per day ($2.5 × 104) by the number of days (1 × 103).
$2.5 × 104 × 1 × 103 = $2.5 × 108
So, the corporation's total profit during this time period is $2.5 × 108.
