An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $1800 and his stock in Company B was worth $1930. The stock in Company A has decreased 16% since last year and the stock in Company B has decreased 20%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).

Answer 1

Let's start by finding the new value of the stock in Company A after the decrease of 16%.

The new value of the stock in Company A is:

0.84 x $1800 = $1512

Similarly, the new value of the stock in Company B after the decrease of 20% is:

0.8 x $1930 = $1544

The total value of the investor's stock account now is:

$1512 + $1544 = $3056

To find the percentage decrease in the investor's stock account, we need to compare the total value of the account now to the total value of the account last year:

($1800 + $1930) = $3730

The percentage decrease is:

[(3730 - 3056)/3730] x 100% ≈ 18.1%

Therefore, the total percentage decrease in the investor's stock account is approximately 18.1%.
