Question

There are 30 homes in Neighborhood A. Each year, the number of homes increases by 20%. Just down the road, Neighborhood B has 45 homes. Each year, 3 new homes are built in Neighborhood B.

Part A: Write functions to represent the number of homes in Neighborhood A and Neighborhood B throughout the years.
( f(x)=30∗0.2x and f(x)=45+3x)

Part B: How many homes does Neighborhood A have after 5 years? How many does Neighborhood B have after the same number of years?
(f(x)=30+0.2(5) and f(x)=45+3(5))

Part C: After approximately how many years is the number of homes in Neighborhood A and Neighborhood B the same? Justify your answer mathematically
