A firm has fixed costs of $5,000. Its short-run production function is y=2x^(1/2), where x is the amount of variable factor it uses.
The price of the variable factor is $80 per unit.
Where y is the amount of output, the short-run total cost function is
a. 5,000 + 5y2
b. 5,000 + 20y2
c. 5,000/y +500
d. y2/4
e. 5,000 + 500y
