P = $ 38,461.54
Equation:
P = A / (1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year,
then, solving our equation
P = 100000 / ( 1 + (0.08 × 20)) = 38461.538461538
P = $ 38,461.54
The principal investment required to get
a total amount, principal plus interest, of $ 100,000.00
from simple interest
at a rate of 8% per year
for 20 years is $ 38,461.54.
This is an aritmetic series;

5 1/2 - 3 5/6 = how much she needs
Make them into common denominator
11/2 = 33/6 - 23/6
33 - 23 = 10
10/6 = 1 2/3 yards
