Answer:
Explanation:
Alpha = 2800 – 1980 =820
Beta = 2750 2900 =250
Gamma = 2600 – 2250= 350
Omega = 1250 – 1485 = 235
Theta = 19503650 =  1700
Change may be increase or decrease. So model
Theta has highest change of production in 2014 over 2013.

% Increase in 2014= $\frac{14851250}{1250}$
x 100% =18.8%
% Increase in 2015 =$\frac{16801485}{1485}$ x 100%
=13.13%
% increase in 2016 = $\frac{18001680}{1680}$ x 100% = 7.14%
The highest percentage increase

20%
% contribution of Beta model in 2011 = $\frac{2500}{11000}$ x 100% =
22.7%
% contribution of Gamma model in 2011 = $\frac{2100}{11000}$ x 100% = 19.09%
% contribution of Omega model in 2011 = $\frac{1400}{11000}$ x 100% = 12.72%
% contribution of Theta model in 2011 = $\frac{2800}{11000}$ x 100% =
