Let us list down first the given.
100 $10 stocks at a market price of $50
declared divedend is 10%
Let us multiply 100 with $50-- that makes up $5000 for the 100 $10 of stocks.
the declared divedend is 10%, so we will get the 10% of $5000.
>change 10% into decimal number by dividing 10 by 100. The quotient would be 0.10.
$5000 x 0.10 is $500.
Therefore, Andre earned $500 in dividends.
