Hello!
Answer:$295.295
Explanation:
Of the statement, we have that the price of the machine decreased 10% every year 
exponentially, so in the first year it real value drops to 90% of the costs. For 5 years, It can be expressed and simplified by the following equation:
We can't use that the percent drop as a percent itself, so we are going to divide 90% by 100%, and it will give us an entire number.

By substituting we have:

Value: $295.245
Have a nice day!
 
        
        
        
I suggest reading them over and over again to remember them. I know it sounds annoying, but trust me, it'll pay off.
        
                    
             
        
        
        
One way you could solve this is to just multiply the top and bottom out so that you get 9/81, reducing it by 9/9 to get 1/9 or option C.
Another way would be to do 

 since dividing numbers with exponents would be subtracting the bottom exponent from the top exponent, provided that the base number (in this case 3) is the same for both. For this method, you would get 

, which is equal to 1/9 or .1 repeating, the same answer that you'd get with the first method.
