p=80000, r=10.5, t=15, m=12
What is your question?
The simplest formula using such values is probably for simple interest: the amount of interest if 80000 is invested for 15 years at 10.5% compounded monthly:
80000*.105/12*15 = 10500
To help you understand the question better, I would like to clarify the variables given in the question:
p = 80000
r = 10.5
t = 15
m = 12
Now, let's break down the variables:
- "p" refers to the principal amount, which in this case is given as 80000.
- "r" refers to the rate of interest, which is given as 10.5%.
- "t" refers to the time period, which is given as 15 years.
- "m" refers to the number of times the interest is compounded per year, which is given as 12.
Based on these variables, it seems like you are dealing with compound interest.
To calculate the compound interest, we can use the formula:
A = P(1 + r/n)^(n*t)
Where:
A = the final amount
P = the principal amount
r = the annual interest rate (expressed as a decimal)
n = the number of times that interest is compounded per year
t = the number of years
Now, let's substitute the given values into the formula and calculate the final amount.
