On the following graph, use the orange points (square symbol) to plot the marginal-cost curve for Tim's Juice Bar. (Note: Be sure to plot from left to right and to plot between integers. For example, if the marginal cost of increasing production from 1 vat of juice to 2 vats of juice is $5, then you would plot a point at (1.5, 5).) Then use the purple points (diamond symbol) to plot the average-variable cost curve starting at 1 vat of juice, and use the green points (triangle symbol) to plot the average-total-cost curve also starting at 1 vat of juice.
