Interest rate = I * 100 / P * R
r = 57.75 * 100 / 550 * 3 
r = 5775 / 1650
r = 3.5
So, your final answer is 3.5%
Hope this helps!

Answer:
see explanation
Step-by-step explanation:
(a)
(f + g)(x) = f(x) + g(x) 
f(x) + g(x) = 6x - 2 + 2x + 4 = 8x + 2
(b)
(f - g)(x) = f(x) - g(x)
f(x) - g(x) = 6x - 2 - (2x + 4) = 6x - 2 - 2x - 4 = 4x - 6
 
        
             
        
        
        
Independent variables must be the amount of cans you buy of cat food. The dependent variable, well that must be the cost. Depending on how many cans you buy, the cost changes! :)
