Ten years at two compoundings per year is 20 compounding periods of time. The initial investment quantity is unknown and can be solved. Call this a.

, not using a Natural Log model (although it could be used instead).

The rate is used as 1+0.085, as a decimal number.







-----The amount to invest.

Each person of the village, of 958 people, would pay dollars, or
dollars each.

My calculations may not have used the accuracy specified in the problem description. Precision might be off a little bit. software calculator was used; not a table of logarithms.

Try checking:
, not too far from 290000.

With P being the present value, we get: _____

Your answer is correct!! The village needs to invest that amount (present value) to raise the $290,000 (future value),

in 10 years. However, I got $ (to 6 decimal places), and $ (rounded to 2 decimal places)

- a difference of just a few cents, maybe caused by rounding. My per-person calculation is exactly what you have.



Good job!!
