An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $2690 and her stock in Company B was worth $2980. The stock in Company A has decreased 20% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).

4300 times 0.03 = 129 (3 percent of 4300)

3040 times 0.20 = 608 (20 percent of 3040)

to find the percentage decreased from total:

4300 + 3040 = 7340

129 + 608 = 737

737/7340 = about 0.10
