Answer:

To determine the number of years it will take for a $5000 investment to reach $7500 at an 8% interest rate, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the future value (in this case, $7500)

P is the principal amount (in this case, $5000)

r is the interest rate (in decimal form, so 8% would be 0.08)

n is the number of times interest is compounded per year (assuming annually, so n = 1)

t is the number of years

We need to solve for t in this equation. Rearranging the formula to isolate t, we get:

t = (log(A/P)) / (n * log(1 + r/n))

Plugging in the values:

t = (log(7500/5000)) / (1 * log(1 + 0.08/1))

Calculating this equation will give us the number of years it will take for the investment to reach $7500.

I hope I helped! If I did, It would mean the world to me if you gave me a special thanks!
