An exponential decay function is:
f=ir^t, f=final amount, i=initial amount, r=common ratio, t=number of times ratio is applied...We can see the initial value is 17000 so all we really have to find is the common ratio, or "rate" as some call it :P  If we look at the second point, when t=1 we can see:
14280=17000r
r=357/425
r=0.84
So in five years the SUV will be worth more than the car by:
17000(0.84^5)-12000(0.89^5)
$408.73  (to the nearest cent)
        
                    
             
        
        
        
Answer:
f(2)=21
Step-by-step explanation:
f(2)=2^3+2*2-4+13=8+4-4+13=8+13=21
 
        
             
        
        
        
You can buy 50 of the cherry candies with all of the 25$ because you do 25 divided by 0.50 and get 50 and then if you would like to check that do 50 x 0.50 and you will still get 25$
        
             
        
        
        
The baker can decorate 
42/30,
which would mean 42 cupcakes in 30 minutes,
and then you would get
1.4 cupcakes per minute. 
Hope this helps and have a nice day:)
