A=future amount
P=present amount
r=rate in decimal
t=time in years

P=270
r=5%=0.05

the equaton is
A=270(0.05+1)^t or
A=270(1.05)^t
for any year, 2009, is year 0, so if you wanted to input the year then
A=270(1.05)^{t-2009} would be for t=what year it was

A. f(x)=270(1.05)^t


b. 2009 to 2020
2020-2009=11 years
t=11
f(11)=270(1.05)^{11}
f(11)=461.792
