A firm faces competitive markets both for its inputs and its outputs. If its long-run supply curve is q = 3p,?

Question

its a true or false, and why. I know it is true but i dont get why...thanks in advance

Answer 1

it si tru
because the competetive marks are for both the input and the output so if output is greater than 50%than output is more
but if the input is 30% more also then the output then also it will not become equal
the input should be more then 70%
because the out put is> input..
