To find the number of years between 1844 to 2015 you have to subtract.
Lets say that x is the # of years in between 1844 and 2015
Then we have:

After doing the subtraction using a calculator or a pencil and paper, you get that:

So 171 years have passed from 1844 to reach to 2015.

Step-by-step explanation:
The function
has a horizontal asymptote which is 
The function
has a horizontal asymptote which is 
The function
has no horizontal asymptote because the numerator has a degree which is higher than the degree of the denominator,
The function

Answer:
What to prove, solve for?

1) Iteration means a repetition of a rule.
a)
Considering that we have the following data:
Rate of increase: 5% per year
-
2) Then we can write out the following:

Plugging into n, the number of years we'll have:
Profits: $30,000 1st year
P: $31.500 2nd year
$33075 3rd year
(...) (...)
b) Since we want to know the predicted profit 15 years from the first year, then we can plug for that:

Note that we have plugged into n, n=15 years. Since the first year was $30,000 the profits.
