Answer:
Step-by-step explanation:
<u>Use formula for continuous interest:</u>
- A =
, where r- interest rate, t- time in years
<u>If A = 3P, and r = 0.085 then the equation is:</u>


- ln 3 = 0.085t
- 1.099 = 0.085t
- t = 1.099 / 0.085
- t = 12.9 ≈ 13 years
A. 1/6
b. 6/3
c. 1
I think those are the answers
8% of x = $18.80
x = 18.80/8%
x = 18.80/0.08
x = $235
