Answer:
the variable cost comes out to be $740
Explanation:
given,
labor per pizza = Â 4$
ingredients per pizza= 3$
electricity cost per pizza = .40$
restaurant rent per month = 2000$
insurance per month = $450
pizza produced per month = 1,000
variable cost  per pizza = labor cost + ingredients cost + electricity cost
variable cost  per pizza=  4$ + 3$ + .40$ Â
                     =  7.4$
variable cost per month = 1000 × 7.4$
                     = 740 $
hence the variable cost comes out to be $740.
