A firm is considering two process alternatives. At A process, fixed costs would be $4,000,000 per year, and variable costs $3.00 per unit. At B process, fixed costs would be $3,600,000 per year, with variable costs of $3.40 per unit. If annual demand is expected to be 9 million units and the selling price $4.50, what is the break-even point for A process and B process? Show your answer support with graph.

ok

Step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
