The Bigshot Inc company has target current ratio of 2.0 but has experienced some difficulties financing its expanding sales in the past few months. At present the firm has current ratio of 2.5 with current assets of $2.5 million. If Bigshot expands its receivables and inventories using short-term line of credit, how much additional short-term funding can it borrow before its target current ratio (of 2.0) is reached?
