How much money has to be invested at 2.3% interest compounded continuously to have $41,000 after 17 years?
a. $27,793.53
b. $27,741.97
c. $27,731.59
d. $27,762.66

For this, we have to calculate how much money has to be invested at 2.3% interest compounded continuously to achieve $41,000 after 17 years

Formula: A= P * ( 1+r)^t
A= $41,000
r=0.023
t= 17
41,000= P * (1+0.023)^17
41,000= P * (1.023)^17
41,000= P * 1.4719
P= 41,000 : 1.4719
P= $27,731.59
Therefore, the answer is C. $27,731.59 
I checked by doing the opposite, and I got $41,000.01, which is the closest to the question

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats
