Sales                    $7,900
Costs                     5,500
Taxable income $2,400
Taxes (25%)            600
Net income        $1,800
Balance Sheet
Current assets          $3,900
Fixed assets                8,600
Total assets             $12,500
Current liabilities       $2,100
Long-term debt           3,700
Equity                          6,700
Total liab. & equity $12,500
Projected Income Statement:
Sales                    $9,085 ($7,900 * 1.15)
Costs                     6,325 ($5,500 * 1.15)
Taxable income $2,760
Taxes (25%)            690
Net income        $2,070
Dividends = 40% $828
Retained earnings $1,242
Projected Balance Sheet
Current assets          $4,485 ($3,900 * 1.15)
Fixed assets                9,890 ($8,600 * 1.15)
Total assets             $14,375
Current liabilities       $2,415 ($2,100 * 1.15)
Long-term debt           4,018 ($14,375 - 2,415 - 7,942)
Equity                          7,942 ($6,700 + $1,242)
Total liab. & equity $14,375
Working capital = $2,070 ($4,485 - $2,415) 
Capital expenditure = $1,290 ($9,890 - 8,600)
External financing needed = Net income minus (working capital plus capital expenditure)
 = $2,070 - ($2,070 + 1,290)
= $1,290
