$4800 is your starting number
it increases 2% every year
how much will it be in 20 years
Formula= ab^x
a is always the starting number
b is the percentage
x is always the length of time
y=4800([this is where it gets tricky])
I never understood why but you have to put 1.02 if increasing and .02 if decreasing.
y=4800(1.02)^20 [20th place(exponent)]
y= $7132.55
A
