Solution:
You have already solved part a and b for it .
Now solve the part C, where we need to use the model 2 , to determine the cost in 2000.
As the model 2 define the cost x years after 1980 .
There are 20 years from 1980 to 2000. So we will plug x = 20 in the model 2 equation and then solve it .
Model 2 equation is given by :
C = -2x2 + 1058x + 14,443
Substitute x = 20 in the above equation ,
C = -2(20)2 + 1058(20) + 14,443
C = -2(400) + 21160 + 14,443
C = -800 + 21160 + 14,443
C = 34803
So th cost would be $34803.
