Answer:
25n
Step-by-step explanation:
It gives us the answer, we just have to simplify it. The problem says that "5n + 20n shows the total amount of money" and we are <em>looking</em> for an expression that shows the total amount of money.
5n + 20n = 25n
Have a nice day!

Answer:
1st problem: b)
2nd problem: c)
Step-by-step explanation:
1st problem:
The formula/equation you want to use is:
where
t=number of years
A=amount he will owe in t years
P=principal (initial amount)
r=rate
n=number of times the interest is compounded per year t.
We are given:
P=2500
r=12%=.12
n=12 (since there are 12 months in a year and the interest is being compounded per month)
Time to clean up the inside of the ( ).
----------------------------------------------------
2nd Problem:
Compounded continuously problems use base as e.
P is still the principal
r is still the rate
t is still the number of years
A is still the amount.
You are given:
P=2500
r=12%=.12
Let's plug that information in:
