(enter your response rounded to two decimal places.) 1.) using the line drawing tool, graph the variable cost curve. label this curve 'vc.' 2.) using the line drawing tool, graph the average variable cost curve. label this curve 'avc.' 3.) using the line drawing tool, graph the marginal cost curve. label this curve 'mc.' carefully follow the instructions above, and only draw the required objects. 0 4 8 12 16 20 24 0.00 2.00 4.00 6.00 8.00 10.00 12.00 14.00 quantity, q, offices cleaned cost, cost per unit, $ mc vc
