The sales are expected to grow by 5% each month thereafter. 2. 50% of the Sales are collected in the same month. 45% of the sales are collected in the following month and remainder are not collected. 3. The Purchases are 20% of sales and paid in the same month. 4. Wages and Salaries are $10,000 each month and paid in the same month. 5. Depreciation expense is $5,000 each month. 6. An equipment worth $100,000 will be purchased with cash in October. 7. The company's debt is $50,000 and the company pays coupon payments in June and December of each year. The coupon rate is 10% per year. 8. Rent Expenses will be $5000 and will be paid at the end of each calendar quarter. Determine the cash surplus and shortages for each month from July to December.
