The formula for the future value VV (in dollars) of an investment earning simple interest is V=p+prtV=p+prt, where pp (in dollars) is the principal, rr is the annual interest rate (in decimal form) and tt is the time (in years). a. Solve the formula for pp.

Respuesta :

The future value of the investment in dollars s
V = p + prt
where 
p = principal, dollars
r = annual interest rate (in decimal form)
t = time, years

To determine p, write the formula as follows:
Factorize p out on the right side.
  V = p(1 + rt)
Divide each side b (1 + rt).
  [tex] \frac{V}{1+rt}=p [/tex]

Answer:
[tex]p= \frac{V}{1+rt} [/tex]
