Write a cost function 0 that calculates the cost of producing the master disc and or: copies. b. If the music videos are sold for $7.20 each, nd a function R that calculates the revenue received from selling a: music videos. c. What is the revenue from selling 8000 videos? d. Assuming that the master disc is not sold, nd a function P that calculates the profit from selling :1: music videos. e. What is the prot from selling 40,000 videos? f. How many videos must be sold to break even? That is, how many videos must be sold for the revenue to equal the cost? g. Graph the cost function, revenue function and profit function on the same axes. Label all the functions, axes, and the point from part (f). Page 1 of 1
