Your average collection period (receivables period) is 10 days and your average account payable period is 50 days. You expect to always spend 40% of the following quarter's sales on purchases of components from suppliers. Wages and other expenses add up to 35% of each quarter's sales.

You have to pay $4 million in interest each quarter, and plan to spend $20 million on new machinery in Q2. You start the year with $3 million in cash.

Assume that each quarter has 90 days, sales occur evenly throughout the quarter and all other cash flows occur at the end of the quarter.
