1. suppose the market share of the four largest firms in the car wash industry are 18, 16, 12 and 10. What is the fore firm concentration ratio? Accepted characters: numbers, decimal point markers, sign indicators(-), spaces, (e.g., as thousand separators, 5,000) "E" or "e"(use in scientific notation). Note: for scientific notation, a period must be used as a decimal point marker. Complex number should be in the form {a+bi} where "a" and "b" need to have explicitly stated values. For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not. 2. The concentration ratio you calculated in question 1 is not concerning the industry. True or False. 3.
