fixed weekly cost of $565.00, and variable costs for making a roast beef sandwich are $0.55. Complete parts (a) through (c) Alocal sandwich store has 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.) C(x) .55x565 (Use integers or decimals for any numbers in the expression.) 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(x) (Simplify your answer. Use integers or decimals for any numbers in the expression.)
