Since it decreases by 36 each year, the change would be 36+36+36+36=36*4=144
For a, we can plug in values for t, so 2000-(200*1)=1800 for the first year,
2000-(200*2)=1600 - do you see the pattern here? It subtracts by 200 every year, so 1600-200=1400 for the third year and 1400-200=1200 for the fourth year.

Answer:
1.
Let f and g concave functions. Then for a in (0,1), and
Now,
This shows that the function f+g is concave.
2. Let f and g concave functions.
This shows that the product of two concave functions isn't concave.
