Suppose you want to predict the value of your Roth IRA Opens in new tab

as you age. Create a function (prob3_3) that takes scalar inputs of the principal amount, contribution amount, annual interest rate and numberof years. Your output will be a vector of the amount in your account the first day each year. Year one begins the day we open the account with our principal contribution. Assume that on the last day of the year, all interest is paid based on the amount in the account over the previous year then the new contribution is added.

Though this can be done without a loop (perhaps more efficiently), your program must use (at least) one.

Hint: use a for loop to generate the account value at the start of each year. E. g. there is $5500 in 2015, then $5500 + $440 (interest on the $5500) + $5500 (deposit) = $11,440 in 2016, then $11,440 +$915.20 (interest on the $11,440) + $5500 (deposit) = $17,855 in 2017, etc.
