P = the principal
t = 25 years the time in years
r = 0.0525 or 5.25% annual rate
m = 1 compounding periods per year
i = 0.0525 or 5.25% interest rate per period
n = t*m = 25 total number of compounding periods
A = $75,000 future value
A = P(1 + i)^n
P(1 + i)^n = A
P(1 + 0.0525)^25 = 75000
by solving we find:
P = $20,869.34
X= 18 and y= 15
point form: (18,15)
It fell by 19%
Use 1173 as your total and then find the percent from 951 and subtract from 100 and that’s the percent that fell
