The answer is C. It is nonlinear because the increase in the “total house built” compared to the increase in the “months passed” does not show a constant rate of change.
All you have to do is make and simplify a fraction. In this case, there are 6 friends going into 4 pears, so the fraction is 6/4. Then we can simplify that because they are both divisible by 2. So if we divide both by 2, our fraction becomes 3/2. Then we make that into a mixed number, with 3 going into 2 once with 1 left over. That means the answer is 1 1/2.
