Budget Drill \#7 Feline Company will begin the month of June with $20,000 in cash on hand. June's projected budget indicates that cash sales will be $50,000 and expenses will be $70,000. The expenses were taken from a budgeted income statement and include $500 of depreciation expense. How much money will Feline need to borrow during the month of June if it wants to begin the month of July with $20,000
