Berlin Inc. expects sales of $300,000 during each of the next three months. It will make monthly purchases of $180,000 during this time. Wages and salaries total $30,000 per month plus 5 percent of monthly sales. The firm expects to make a tax payment of $60,000 in the first month and a $45,000 purchase of fixed assets in the second month and to receive $24,000 in cash from the sale of an asset in the third month. All sales and purchases are for cash. Beginning cash and the minimum cash balance equal zero.
