The average cost per item in dollars to make x video games is given by M = 5x + 2,000,000 over x and the average cost per item in dollars to package the same video game is given by...

Question

P = 2x + 500,000 over x

Write an equation C that gives the total cost per item of making and packing x video games.

C = blank (Simplify your answer)

Answer 1

M=5x+2000000/x, P=2x+500000/x.

Total cost C_T=M+P=7x+2500000/x. This is the cost in dollars of x games (making and packing).

The unit cost C in dollars is (7x+2500000/x)/x=7+2500000/x² per game, including packing.
