A local sandwich store has a fixed weekly cost of $575.00, 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: T
C(x) = (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
weekly profit function, P. (Hint: The profit function is the difference between revenue and cost functions.)
P(x) =

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 maxin
The maximum weekly profit is $ when sandwiches are sold.
(Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.)
