Question

a local sandwich store has a fixed weekly cost of $545.00, and variable costs for making a roast beef sandwich are $0.65. let x represent the number of roast beef made and sold each week. write the weekly cost function,c, for the local sandwich store

Answer 1

The total cost, c, will always have the $545 included. The additional amount that "changes" each week is the variable portion and is dependent on how many sandwiches are sold, x.

The weekly cost would be represented by:

c = $0.65 • x + $545
