If i read this correctly the amount of money at the end of 18 years should be $23,997.60
Find an interest by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this examplee P = $110, i = 1212% and t = 18 years, so
III=P⋅i⋅t=110⋅12.12⋅18=23997.6
