What is the formula to determine the following:

Assets decreased by $25,000 during the period. Liabilities increased by $15,000 during the period. Cash dividends declared during the period were $52,000. Expenses were $194,900. Revenue for the period was.

a. $199,100
b. $218,900
c. $206,900
d. $182,100

c. $206,900

Jan 1 = 100 = 50 + 50
Dec 31 = 75 = 65 + 10 (decrease of 40)

Beg 50,000
+ Revn??
- Exp 194,900
- Div 52,000
End 10,000

Revenues = 206,900
