Problema Solution

how many years will it take for $480 to grow to $1,057.19 if it's invested at 8 percent compounded annually.

Answer provided by our tutors

P = $480 the principle

i = 8% or 0.08

A = $1,057.19 the future value

t = years


A = P(1 + i)^t


1,057.19 = 480(1 + 0.08)^t


1.08^t = 1,057.19/480


t = (ln 1,057.19/480)/ (ln(1.08))


t = 10.26 years
