Consider the following table:

Paulie's Pizzeria, 2020
Income Statement		Balance Sheet
Sales	$600	Current Assets	$300
Costs	$450	Net Fixed Assets	$350
Taxable Income	$150	Total Assets	$650
Taxes (21%)	$31.50
Net Income	$118.50	Total Debts	$400
Dividend Payments	$35.55	Total Equity	$250
Addition to Retained Earnings	$82.95	Total Liab & Equity	$650

If we assume that in 2021, Paulie's Pizzeria will have 1) a 20% increase in both sales and costs, 2) the tax rate that remains the same at 21%, 3) the dividend payout rate that remains the same at 20%, and 4) a 20% increase in the amount of total assets, what is the plug variable in this case? Assume that the amount of total equity can increase only through addition to retained earnings, and that there will be no issuance or repurchase of the firm's shares.

a)Dividend Payments

b)Total Debts

c)Total Equity

d)Addition to Retained Earnings

Same facts as above: how much external financing is needed in this case, and where will this external financing be added?

a) $47.05 to Total Equity

b) $47.05, to Total Debt

c) $30.46, to Total Debt

d) 30.46, to Total Equity
