A local sandwich store has a fixed weekly cost of $570.00, and variable costs for making a roast beef sandwich are $0.45. Complete parts (a) through (c). a. Let x represent the number of roast beef sandwiches made and sold each week. Write the weekly cost function, C, for the local sandwich store. (Hint The cost function is the sum of fixed and variable costs.) (Use integers or decimals for any numbers in the expression.) C(x)= b. The function R(x) = -0.001x +3x describes the money that the local sandwich store takes in each week from the sale of x roast beef sandwiches. Use this revenue function and the cost function from part (a) to write the store's weekly profit function, P. (Hint The profit function is the difference between revenue and cost functions.) P)= (Simplify your answer. Use integers or decimals for any numbers in the expression.) C. Use the store's profit function to determine the number of roast beef sandwiches it should make and sell each week to maximize profit. What is the maximum weekly profit? sandwiches are sold. The maximum weekly profit is $ (Use integers or decimals for any numbers in the expression.
