It must be about the origin in order to do that
Answer:
first, u need to know the formula for compound interest, which is:

where A is the final amount
P- initial amount
r- percent compounded(interest)
and
n- number of years
so
we have

3.8/100 = 0.038
1+0.038 =1.038
1.038^4 = 1.160885573136
475 * 1.160885573136 = 551.4206472396
approximately $551.42
All because -2.22 is a real number, it’s a rational number because it can stop and a integer because it’s negative
The answer too your question is 65 it is equal to the square root of 65
