Q. An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6880 \$ 6880 and his stock in Company B was worth $6600 \$ 6600 . The stock in Company A has decreased 10%10\% since last year and the stock in Company B has decreased 1% 1 \% . What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).\newlineAnswer:
  1. Calculate Decrease Company A: Calculate the decrease in value for the stock in Company A.\newlineOriginal value of Company A stock: $6880\$6880\newlinePercentage decrease: 10%10\%\newlineDecrease in value = Original value ×\times Percentage decrease\newlineDecrease in value = $6880×0.10\$6880 \times 0.10\newlineDecrease in value = $688\$688
  2. Calculate New Value Company A: Calculate the new value of the stock in Company A after the decrease.\newlineNew value of Company A stock = Original value - Decrease in value\newlineNew value of Company A stock = $6880\$6880 - $688\$688\newlineNew value of Company A stock = $6192\$6192
  3. Calculate Decrease Company B: Calculate the decrease in value for the stock in Company B.\newlineOriginal value of Company B stock: $6600\$6600\newlinePercentage decrease: 1%1\%\newlineDecrease in value = Original value ×\times Percentage decrease\newlineDecrease in value = $6600×0.01\$6600 \times 0.01\newlineDecrease in value = $66\$66
  4. Calculate New Value Company B: Calculate the new value of the stock in Company B after the decrease.\newlineNew value of Company B stock = Original value - Decrease in value\newlineNew value of Company B stock = $6600\$6600 - $66\$66\newlineNew value of Company B stock = $6534\$6534
  5. Calculate Total Original Value: Calculate the total original value of the stocks.\newlineTotal original value = Value of Company A stock + Value of Company B stock\newlineTotal original value = $6880\$6880 + $6600\$6600\newlineTotal original value = $13480\$13480
  6. Calculate Total New Value: Calculate the total new value of the stocks.\newlineTotal new value = New value of Company A stock + New value of Company B stock\newlineTotal new value = $6192\$6192 + $6534\$6534\newlineTotal new value = $12726\$12726
  7. Calculate Total Decrease: Calculate the total decrease in value of the stocks.\newlineTotal decrease in value = Total original value - Total new value\newlineTotal decrease in value = $13480\$13480 - $12726\$12726\newlineTotal decrease in value = $754\$754
  8. Calculate Total Percentage Decrease: Calculate the total percentage decrease in the investor's stock account.\newlineTotal percentage decrease = (Total decrease in value/Total original value)×100%(\text{Total decrease in value} / \text{Total original value}) \times 100\%\newlineTotal percentage decrease = ($754/$13480)×100%(\$754 / \$13480) \times 100\%\newlineTotal percentage decrease \approx 55.5959\%
