Problem $18-15$ Capacity Use and External Financing $($LO$2)$

The $2019$ financial statements for Growth Industries are presented below.

Sales and costs are projected to grow at $20\%$ a year for at least the next $4$ years. Both current assets and accounts payable are

projected to rise in proportion to sales. The firm is currently operating at full capacity, so it plans to increase fixed assets in proportion

to sales. Interest expense will equal $10\%$ of long$-$term debt outstanding at the start of the year. The firm will maintain a dividend payout

ratio of $0\mathrm{.}50.$

If Growth Industries is operating at only $75\%$ of capacity, how much can sales grow before the firm will need to raise any external

funds? Assume that once fixed assets are operating at capacity, they will need to grow thereafter in direct proportion to sales.

Note: Do not round intermediate calculations. Round your final answers to the nearest whole dollar amount.
