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? Write the answer in scientific notation.
To find the total profit, 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
Total profit = Profit per day × Number of days
Total profit = $2.5 × 10^4 × 1 × 10^3
When multiplying numbers in scientific notation, we add the exponents and multiply the coefficients.
Total profit = $2.5 × 1 × 10^4 × 10^3
Total profit = $2.5 × 1 × (10^4 × 10^3)
Total profit = $2.5 × 1 × 10^7
Thus, the corporation's total profit during this time period is $2.5 × 10^7.
