Need help with screenshots 14 through 23. Note that I accidentally numbered two photos as "screenshot 22," just put in your solutions "22a" and "22b" so I know where your solutions belong. Thank you! And let me know below in the comments if you need anything else. Much appreciated!

14 The Cobb-Douglas production function for a particular product is N(x,y) = 80x0'6y0'4, where x is the number of units of labor and y is the number of units of capital required to produce N(x, y) units of the product. Each unit of labor costs $40 and each unit of capital costs $80. If $200,000 is budgeted for production of the product, determine how that amount should be allocated to maximize production. Production will be maximized when using :I units of labor and units of capital.
