A company made one of the largest single purchases of​ long-distance telephone time in history. It purchased 45million minutes at a total cost of $1,800,000. If the company resells the phone time at an average of 6 cents per​ minute, how much profit will it make on the​ purchase?

The company purchased 45 million minutes at a total cost of $1,800,000.

If the company resells the phone time at an average of 6 cents per minute, it will make a profit of:
Profit = (resale price - purchase price) * number of minutes
Profit = (0.06 - 0.00) * 45,000,000
Profit = 0.06 * 45,000,000
Profit = $2,700,000. Answer: \boxed{2,700,000}.
