Answer:
Step-by-step explanation:
let us assume the investment is compounded over the given period
Given data
Final amount A= $20,000
Rate r= 12%= 0.12
Time t= 10 years
principal=?
The compound interest formula is
[tex]A= P(1+r)^n^t[/tex]
Substituting our given data we have
[tex]20000= P(1+0.12)^1^0\\20000= P(1.12)^1^0\\20000= P(3.105)\\[/tex]
Dividing both side by 3.105 to find P
[tex]P=\frac{20000}{3.105} \\P= 6441.22[/tex]
Principal is $6441.22
