Assume the short run variable cost function for Japanese beer $is$

VCequals$0\mathrm{.}8q$ Superscript $0\mathrm{.}8.$

$If$ the fixed cost $(F)is$ $$600$ and the firm produces $700$ units, determine the total cost $of$ production $(C),$ the variable cost $of$ production $(VC),$ the marginal cost $of$ production $(MC),$ the average fixed cost $of$ production $(AFC),$ and the average variable cost $of$ production $(AVC).$ What happens $to$ these costs $if$ the firm increases its output $to750?$

Assuming the firm produces $700$ units, the variable cost $of$ production $(VC)is$
