A coffeehouse sells a pound of coffee for $8.25. Expenses are $3 comma 500 each month, plus $3.50 for each pound of coffee sold. (a) Write a function R(x) for the total monthly revenue as a function of the number of pounds of coffee sold. (b) Write a function E(x) for the total monthly expenses as a function of the number of pounds of coffee sold. (c) Write a function (RminusE)(x) for the total monthly profit as a function of the number of pounds of coffee sold. (a) The revenue function is R(x)equals nothing. (Simplify your answer. Use integers or decimals for any numbers in the expression. Do not include the $ symbol in your answer.) (b) The expense function is E(x)equals nothing. (Simplify your answer. Use integers or decimals for any numbers in the expression. Do not include the $ symbol in your answer.) (c) The profit function is (RminusE)(x)equals nothing. (Simplify your answer. Use integers or decimals for any numbers in the expression. Do not include the $ symbol in your answer.)
