4. When a firm enters into a loan agreement with its bank, it is very common for the agreement to have a restriction on the minimum current ratio the firm has to maintain. So, it is important that the firm be aware of the effects of its decisions on the current ratio. Consider the situation of Advance Auto Parts (AAP) in 2009. The firm had total current assets of $1,807,626,000 and total current liabilities of $1,364,994,000.

a. What is the firms current ratio?

b. If the firm were to expand its investment in inventory and finance the expansion by increasing accounts payable, how much could it increase its inventory without reducing the current ratio below 1.2?

c. If the company needed to raise its current ratio to 1.5 by simultaneously reducing its investment in current assets and reducing its accounts payable and short-term debt, how much would it have to reduce current assets to accomplish this goal?
