On the following graph, plot Douglas Fur's average total cost curve $($ATC$)$ using the green points $($triangle symbol$).$ Next, plot its average variable cost curve $($AVC$)$ using the purple points $($diamond symbol$).$ Finally, plot its marginal cost curve $($MC$)$ using the orange points $($square symbol$).$

$($Hint: For ATC and AVC, plot the points on the integer: For example, the average total cost of producing one pair of boots is $$200,$ so you should start your average total cost curve by placing a green point at $(1,200).$ For marginal cost, plot the points between the integers: For example, the marginal cost of increasing production from zero to one pair of boots is $$80,$ so you should start your marginal cost curve by placing an orange square at $(0\mathrm{.}5,80).)$

Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.
