The answer is 3. If you find the unit rate of white to blue paint and multiply it by 4.5 it would come out to 3.000007 or something minute like that.
 
        
             
        
        
        
8:64 = 1:8 (divide both sides by 8)
        
             
        
        
        
We need more information or a picture please :)
        
             
        
        
        
(a) Using Newton's Law of Cooling, 

, we have 

 where T is temperature after T minutes.
Separate by dividing both sides by T - 75 to get 

. Integrate both sides to get 

.
Since 

, we solve for C: 

So we get 

. Use T(30) = 150 to solve for k:

So 

But choose Positive because T > 75. Temp of turkey can't go under.

(b)
