Answer:
-1.1
Explanation:
Data provided in the question:
Average temperature is rising at a rate,
= 0.15°C/year
Rate of change rainfall,
= - 0.1 cm/year
= -2
= 8
Now,
we need to calculate 
since,
The wheat production (W) is dependent on the rainfall (R) and the Temperature (T)
thus, Using the chain rule , we have
=
+ 
on substituting the respective values, we get
= -2 × 0.15 + 8 × (-0.1)
or
= -0.3 - 0.8
or
= -1.1
