If question requires you to show calculatio , what information is needed to show? I think the cfa model answer is too detailed.

for example, like 2011, q4, show calculation using Cobb-douglas, is it required to show like below?

Projected annual GDP growth rate = growth in total factor production + output elasticity of capital x growth…l

= 2.8% + 0.4 x 3.6%…

We need to write the formula in word?
