Remember that in PEMDAS, you do the parentheses first.
1. For each answer choice, do whatever is in the parentheses first.
2. Multiply that number to the one outside the parentheses 
Hint: For this problem, If all the signs in the answer choice are multiplication, they will equal the same number.

Answer:
$429.75
Step-by-step explanation:
First, find the tax rate on the sale of the boat:  Let r represent that rate.  Then, 
$12,500r = $562.50.  Solving for r, we get r = $562.50 / $12,500 = 0.045
The tax rate is 0.045, or 4.5%.
Applying this tax rate to a boat selling for $9,550:
0.045($9,550) = $429.75.  This is the amount of tax on the 2nd boat.
 
        
             
        
        
        
The polynomial can't be factored because they are all rational numbers.
        
             
        
        
        
28: 1, 2, 4, 7, 14, 28
40: 1, 2, 4, 5, 8, 10, 20, 40
The common factors are 1, 2, and 4.
You can use a factor rainbow to help you find the factors (:
