Answer:
Principal = $1,000
Rate of interest = 14% = 0.14
Time = 3 years

A = Amount or future value
P = Principal
r = rate of interest in decimals
t = time
Substitute the values in the formula


Future Value is $1481.544
Compound interest = Amount - Principal = $1481.544- $1000 = $481.544
Formula of simple interest : 
Substitute the values :


So, Simple interest = $420
Compound interest - Simple interest
= $481.544- $420
= $61.544
So, Compound Interest is $61.544 more than simple interest.
You rearrange the equation getting x = 9 * 3 which equals 27. So x = 27
Or just do 9*3 to get 27.
