The document provides steps to solve two problems: 1) It calculates that the town of Normalville must build 39 new homes based on population growth between 2004 and 2008. It does this by taking the population difference and dividing by 4, then rounding up. 2) It introduces an exponential function that can model population growth over time, using variables for initial population, final population, and Euler's constant.

1. Solution!

2. a) How many new homes must the town of
Normalville build. Round to the nearest whole house.
H(p) P(2008) ­ P(2004) Evaluate number of houses
for the number of population.
4
H(p) 1116 ­ 963
4
H(p) 153 Dividing the number of people by 4
because for every 4th person a house
4 must be built.
The actual number of houses need to
H(p) 38.25 39 be built is 38.25, but you cannot
make a quarter of a house, so you
have to round up.
