<u>Compound Interest</u>
This is a well-know problem were we want to calculate the regular payment R needed to pay a principal P in n periods with a known rate of interest i.

Solving for R

Where Fa is computed by

We'll use the provided values but we need to convert them first to monthly payments




Thus, each payment is


30% Bc there are 30 boys and 90 girls or it’s 10% boys
General term of a geometric sequence is
a(n)=a(1)×r^(n-1)
a1=5
a2=5×6=30
a3=5×6²=180
a4=5×6³=1080
