Question

I NEED HELP PLEASE!!! An investor has an account with stock from two different companies. Last year,
her
stock in Company A was worth $2300 and her stock in Company B was worth $3080.
The stock in Company A has decreased 9% since last year and the stock in Company
B has decreased 25%. What was the total percentage decrease in the investor's stock
account? Round your answer to the nearest tenth (if necessary).

Answer 1

Answer:

81.8%

Step-by-step explanation:

Last year:

Company A stock + Company B stock = total amount of stock:

$2300 + $3080 = $5380

This year:

Company A stock: 2300 - (2300*0.09) = 2093

Company B stock: 3080 - (3080*0.25) = 2310

Company A stock + Company B stock = total amount of stock:

$2093 + $2310 = $4403

Total amount of decrease from last year:

$\frac{4403}{5380} * 100 = 81.8$ percent
