Answer :
The interest rate required in order for Jaxon to end up with $6400 is 4.6%.
Simple interest is a method for figuring out how much interest was paid on a sum of money during a specific time period at a specific rate. Simple interest has a constant principle amount. Simple interest is a clear-cut and simple method for computing financial interest.
Compound monthly refers to a loan's interest rate, which is charged in installments each month and added to the principal.
Jaxon invested $3500 and leave the account for 13 years.
The interest is compounded annually and the final amount in the account after 13 years is $6400.
Then, using the formula:
A = Pe^(rt)
6400 = 3500 × e^(r × 13 )
64 = 35 × e^(r × 13 )
e^(r × 13 ) =
13r = ㏑( 64/35)
r = 0.0464
Hence, the interest rate is 4.6%.
