3. LOOKING FOR HELP WITH LETTER B

A local sandwich store has a fixed weekly cost of $535.00, 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.) C(x) = 535 +0.45x (Use integers or decimals for any numbers in the expression.) b. The function R(x) = -0.001x2 + 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.)

Answer 1

Given c (al=535+ 0.45* R(x) = -0.obln²+3x Profit function p(nl= R(x)-((a) -0.001x²+3a-(535+0.45x) :-0.001x²+32-535-0.450 -0.001x²+ 2.55a- 535 Ars
