Question 1148011
formula for this would be A = P * e ^ (r * t)
A is the future value.
P is the present value.
r is the interest rate per year = percent interest rate per year / 100.
t is the number of years.
in this formula, solve for P to get:
P = A / e ^ (r * t)
when A = 15000 and r = 4.9% / 100  = .049 and t = 4, the formula becomes:
P = 15000 / e ^ (.049 * 4).
solve for P to get:
P = 12330.18352
to have 15,000 dollars in 4 years compounded continuously at 4.9% per year, 12,330.18352 dollars would need to be invested now.
