Answer 1

Answer:

d 20.4 years

Step-by-step explanation:

The equation is

A = Pe ^(rt)

We know that r = .034

We want the money to double  so A = 2P

Substitute in

2P = P e ^(.034t)

Divide by P

2P/P = P/P e ^(.034t)

2 = e^ (.034t)

Take the natural log on each side

ln (2) = ln(e^ (.034t))

ln (2) = .034t

Divide by .034

ln (2) /.034 = .034t/.034

ln (2)/.034 = t

20.3867 =t
