question
What is the marginal product of an input
answer
The increase in quantity of output from an additional unit of the input (holding other inputs constant)
question

answer
MPL=ΔQ/ΔL
question
How do we get total cost function
answer
By adding up the costs of all inputs at each quantity
question
What is total cost
answer
Fixed costs + Variable costs
