Answer:
time required is 5.0683 years
Explanation:
given data
initial investment principal (P) = $10,000
grow amount (A) = $15,000
rate of interest (r) = 8%
to find out
time period (t)
solution
we know the formula for this
amount = principal ×
.................1
put the value amount , principal and r in equation 1 and we get time
amount = principal ×

15000 = 10000 ×
![e^(0.08t)](https://img.qammunity.org/2020/formulas/mathematics/college/yd0x8s1ym5nquvmhwxmx7ixy5pgj77urdy.png)
= 15000/10000
take ln both side and we get
ln
= ln 1.5
0.08t = ln 1.5
t = ln 1.5 / 0.08
t = 5.068314
time required is 5.0683 years
