Question 3:
Nicole wants area rugs and painting for her new house. She has been given a budget of $7,200 for this purpose. The area rugs that she wants can be purchased for $900 and paintings from a local Wyoming artist can be purchased for $400.
a. Using Excel's charting tool, draw Nicole's budget constraint.
Write a budget constraint equation for Nicole:
b. For a limited time only Nicole can purchase area rugs at a price of $600, the cost of the paintings remain constant and now her budget has decreased to $6,000. Using Excel's charting tool, draw a new budget constraint curve. Would the budget constraint curve be likely to shift to the left or right?
Write a new budget constraint equation for Nicole:
Question 4:

a. Calculate the total fixed costs, total variable costs, average fixed costs, average variable costs, average total costs, and marginal costs.
b. Plot the cost curves. (Hint: Graph total costs curves separate from average costs and marginal cost curves).
c. At what quantity of output does marginal cost = average total cost and quantity of output in which marginal cost = average variable cost.
