Question

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $5200 and his stock in Company B was worth $6450. The stock in Company A has decreased 3% since last year and the stock in Company B has decreased 6%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).

Answer 1

4.5%

Explanation:

The total percentage decrease in the investor's stock account was 4.5%. This is calculated by taking the decrease in Company A (3%) and Company B (6%) and adding them together to get a total decrease of 9%. This percentage is then divided by two (since there are two companies) to get 4.5%.
