The total cost C fora manufacturee during a given time period is a function of the number N of items produced during that period. To determine a formula for ehe total cost, ne need to know the Thanufacturer's fixed costs (covering things such as plant maintenance and insurance), as well as the cost for each unit produced, ahich is called the vanisole cost. To find the tocal cost, we muliply the variable cost by the number of items produced during that period and then add the fixed costa. Suppose that a manufacturer of widgets has foved costs of $7000 per month and that the varlable cost is $14 per nidget (so it coses $14 to produce 1 widget). (a) Use a formula to express the total cost C of this manufacturer in a month as a function of the number of widgets produced in a month. (Use N as the number of widgets pmeduced ia a month.) c = (b) Express using functional notaten the total cong is there are 173 w dgets produced in a monthi, Calculate the total cost if there are 175 widgets produced in a month. 5
