Answer:?-54-42=?
Step-by-step explanation:
Answer:
We get the value of Principal amount i.e initial investment = $61640
Step-by-step explanation:
Interest rate r = 3.59% or 0.0359
Compounded quarterly n = 4
Future Amount A = 117,300
Time t = 18 years
We need to find initial investment i,e Principal Amount P
The formula used is: 
Putting values and finding P

So, We get the value of Principal amount i.e initial investment = $61640
To solve for the true hourly wage simply add the 2 rates together.
20 dollars/500 hours = 2/50 = 0.04 dollars per hour.
The true rate would be $18.000 + $0.04 = $18.04 per hour.
