If $7500 is invested at an interest rate of 5% each year, what is the value of the investment in 4 years? write an exponential function and solve.

An exponential function is:      

Value of the investment in 4 years is, $9,116.29688

Step-by-step explanation:

Using formula of an exponential function

            .....[1]

where

A(t) is the amount

P is the principal

r is the rate of interest in decimal

t is the time in years

As per the statement:

P = $7500

r = 5% = 0.05

t =4 years

then substitute these in [1] we get;

⇒

Simplify:

Therefore, the value of the investment in 4 years is, $9,116.29688

pi x^2

step-by-step explanation:

pi times x squared
