Answer:
A. 30800
B.39600
C. 17600
Step-by-step explanation: 0.12*$35000= 4200 35000-4200 = $30800
$45000*0.12=$5400 $45000-$5400= $39600
$20000*0.12=$2400 $20000-$2400= $17600
Answer:

Step-by-step explanation:
Let use the following trigonometric identities:

Then, the equation is simplified by substituting its components:





1/2. If you take out the units you're left with 5 to 10 or 5/10. 5 is half of 10 therefore the simplest form would be 1/2.
