Consider an industry that produces 400,000 units of output. A total of six firms produce this output, broken down as follows: Calculate this industry's four-firm concentration ratio. We'll reuse this information in the next question. Enter only numbers, a decimal point, and/or a negative sign as needed. Round your onswer to two decimal places as necessary. Express your answer "as a percent, but without the percentage sign." In other words, if your answer is 99.99 percent, enter only 99.99 in the blank, Again, please consider the industry that produces 400,000 units of output from the last question. A total of six firms produce this output, broken down as follows: If we use 80% as the cutoff (as we have on assignments), we will conclude that this industry an oligolopy: in other words, output is
