We know that:
Neighbourhood A = 30 homes and the number increases by 20% each year
Neighbourhood B = 45 homes, and each year 3 new homes are built.
A.
Neighbourhood A and B are as follows:
For neighbourhood A: f(x) =
For neighbourhood B: f(x) = 45 + 3x
B.
Over five years:
Neighbourhood A has =
Neighbourhood A =
Neighbourhood A = 74.65 homes
Neighbourhood B: = 45 + 3(5)
Neighbourhood B: = 45 + 15
Neighbourhood B: = 60 homes
C.
To determine how many years the number of homes are the same for neighbourhood A and B, we need to equate both together.
So x= 3.3
so, hence after 3.3 years, the number of homes will be the same.
