To solve:
State tax is 5% - you need to first find how much of the $4,000 goes to state tax: $4,000 x 5% = $200
Next find the Federal tax of 25% - $4,000 x 25% = $1,000
Next add the two tax amounts that are being taken out of Annie's paycheck together: $1,000 + $200 = $1,200
Finally, subtract the tax amount of $1,200 from $4,000 = $2,800
The real value of Annie's profit is $2,800 due to the amount of taxes taken out of her paycheck.
