Given that Kyle has received 900$ in cash as a gift and Kyle wants to invest that money in CD with 4% compound interest which is being compounded annually.

That means interest rate = 4% =
(4)/(100) = 0.04 in decimals.

Since interest is compounded annually, we have to use compound interest formula.

That is amount after time t is
A= P(1+(r)/(n)) ^(nt)

Where P- initial amount = 900

r= rate of interest in decimals = 0.04

n= number of times interest is compounded per year = 1

t= number of years the money is invested = 5

Hence A =
900(1+(0.04)/(1) )^(1*5)  = 900(1.04)^(5)

= $1094.9876

So, at the end of five year period, Kyle will have 1094.9876$ to put down in his car.
