Gwen received a $900 bonus at work and decided to invest this money in the stock market.  She spent one-third of her bonus on stock A, one-third on stock B, and the remaining one-third on stock C.   After one year, stock A and stock B had doubled in value, while stock C had lost half of its value.  At the end of the year, how much were Gwen's stocks worth, in dollars?
One-third of her bonus was $900/3 = $<<900/3=300>>300.
After one year, stock A doubled in value and was worth $300*2 = $<<300*2=600>>600.
After one year, stock B doubled in value and was worth $300*2 = $<<300*2=600>>600.
After one year, stock C had lost half its value and was worth $300/2 = $<<300/2=150>>150.
Altogether, at the end of the year, Gwen's stocks were worth $600+$600+$150 = $<<600+600+150=1350>>1350

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

Jason is making sand art. He wants to fill a rectangular patch 6 inches by 7 inches with blue sand, and a square path 5 inches by 5 inches with red sand. If it takes 3 grams of sand to fill one square inch, how many grams of sand does Jason need?First find the area of the first patch: 6 inches * 7 inches = <<6*7=42>>42 inches
Then find the area of the second patch: 5 inches * 5 inches = <<5*5=25>>25 inches
Then add those two amounts to find the total area Jason needs to cover: 42 inches + 25 inches = <<42+25=67>>67 inches
Then multiply that area by the number of grams per square inch to find the total amount of sand needed: 67 inches * 3 grams/square inch = <<67*3=201>>201 grams

Darrel has 76 quarters, 85 dimes, 20 nickels and 150 pennies.  If he drops all of his money into a coin-counting machine, they will convert his change into dollars for a 10% fee.  How much will he receive after the 10% fee?He has 76 quarters so that’s 76*.25 = $<<76*.25=19.00>>19.00
He has 85 dimes so that’s 85*.10 = $<<85*.10=8.50>>8.50
He has 20 nickels so that’s 20*.05 = $<<20*.05=1.00>>1.00
He has 150 pennies so that’s 150*.01 = $<<150*.01=1.50>>1.50
All total he has 19+8.5+1+1.5 = $<<19+8.5+1+1.5=30.00>>30.00
They charge a 10% fee to count and convert his change into dollars so they will charge him .10*30 = $3.00
He had $30.00 and they charged him $3.00 in fees so he now has 30-3 = $<<30-3=27.00>>27.00
