Solution

Using technology, we get              
              
slope = b1 =   7.6   [ANSWER]  
intercept = b0 =   1246.666667   [ANSWER]

***************************          
              
Thus, the regression line is              
              
y^ =    1246.666667 + 7.6 x    [ANSWER]

***************************

What is the variable cost per unit produced (to 1 decimal)?

$ 7.6 [ANSWER]

Also, getting the correlation,              
              
r =    0.979127101          
              
Thus, the coefficient of determination is              
              
r^2 =    0.9587   [ANSWER]

****************************

It is 95.87% [ANSWER]

Thus, if x =    500          
              
Then              
              
y^ =    5046.67 [ANSWER]
