Answer:
It cooled 58.4 degrees
Step-by-step explanation:
T(t) = 68 + 144e ^(-.052t)
We want to find the value when t= 10
T(10) = 68 + 144e ^(-.052*10)
         = 68 +85.611
  T(10)         =153.611
We also need to know 
T(0)= 68 + 144e ^(-.052*0)
        =68+144
         =212
We want to know how much it cools
That would be the temperature at  time 0 minus the temperature at  time 10
T(0) - T (10)
212-153.611
58.389
To the nearest tenth
58.4 degrees

Step-by-step explanation:
It's just basic of domain and range just check out the domain and range you can get your answer .
Only option (B) and (D) satisfy in the given range and domain 
 
        
             
        
        
        
From what I think of this question, i think of 9x37 and 8x37 OR 9/37 and 8/37. either way
8x37=296
9x37=333
9/37=0.2432
8/37=0.2162
