Answer
Beet farm average subsidies: ${$18,750}$
Sugarcane farm average subsidies: ${$1,875,000}$
Work Step by Step
Each small group gets half of the ${$75,000,000}$ allocated in subsidies.
So, each group gets ${$37,500,000}$.
For each of 2000 beet farms that each receives in subsidies, that can be found with the following: $\frac{$37,500,00}{2000}$ = ${$18,750}$
Again, for each of 20 sugarcane farms that each receives in subsidies, that can be found with the following: $\frac{$37,500,00}{20}$ = ${$1,875,000}$
