Sorry but grade math is this so I can have a better understanding
Answer:
In 2003, the population was 59000 and the population has been growing by 1,700 people each year.
A.
The equation will be:
59000+1700x = (population 'x' years after 2003)
For x, you plug in the amount of years after 2003.
Like if it is the year 2003, the population is 
= 59000
when it is year 2005, the population is 
= 62400
B.
The town's population in 2007 will be :

Population = 65800
C.
=> 
x = 11
Means 
Hence, by year 2014 the population will be 77700.
