"Here are a new company’s Revenues and Expenses for its first six months of operations
Month 1 $9,000 $18,000
Month 2 $12,000 $18,000
Month 3 $21,000 $18,000
Month 4 $24,000 $28,000
Month 5 $29,000 $28,000
Month 6 $36,000 $31,000
Please show the company’s cash surplus or shortfall for each of the six months as well as a running total. What is the company’s maximum working capital requirement? In other words, what is the amount that needs to be added to start-up costs to cover anticipated cash shortfalls? This should be the lowest negative number in the running total."
How do I find this? What equation do I use?
