oL ey I You pay your secretary $9.25 per hour. A stamped envelope costs 40 cents, and paper costs 8 cents per page (2) How much does it cost to prepare and mail a 3-page letter If your secretary spends 2 hours on ty| $ ping and corrections? (b) Use a formula to express the cost of preparing and mailing a letter as a function of the number of pages in the letter and the time it takes your secretary to type it. (Let h be the number of hours spent typing the letter, p be the number of pages used, and C be the total cost.) C= (c) Use the function you made in part (b) to find the cost of preparing and mailing a 2-page letter that it takes your secretary 35 minutes to type. (Nol two decimal places.) te: 35 minutes is 35/60 hour. Round your answer to $ Need Help? 4. [-/1 Points] MY NOTES CRAUDCOLALGS 1.4.EX.015.MI. The total cost C for a manufacturer during a given time period is a function of the number N of items produced during that period. To determine a formula for the total co fixed costs (covering things such as plant maintenance and insurance), as well as the cost for each unit produced, which is called the variable number of items produced during that period and then add the fixed costs. PRACTICE ANOTHER st, we need to know the manufacturer's cost. To find the total cost, we muitiply the variable cost by the Suppose that a manufacturer of widgets has fixed costs of $7000 per month and that the variable cost is $12 per widget (so it costs $12 to produce 1 widget). (a) Use a formula to express the total cost C of this man ufacturer in a month as a function of the number of widgets produced in a month. ( Use N as the number of widgets produced in a month.) c= = 1 (b) Express using functional notation the total cost if there are 200 widgets produced in a month o ) Calculate the total cost If there are 200 widgets produced in a month. $ Need Help? s [
