Jackson will have approximately $2,696.04 on deposit in his savings account at the end of 4 years, assuming he makes no withdrawals during that period.
To calculate the future value of Jackson's savings account after 4 years with monthly compounding interest, you can use the future value of an ordinary annuity formula:

where:
FV is the future value of the annuity,
P is the monthly deposit (in this case, $50),
r is the monthly interest rate (in decimal form),
n is the number of compounding periods per year (in this case, 12 since it's compounded monthly),
t is the number of years.
In this scenario, P=50, r=0.03/12 (monthly interest rate), n=12, and t=4.

Now, calculate this expression to find the future value.



The correct result is approximately $2,696.04.
