Practice Checking Account Model

Construct a Stella model of a banking account with deposits and withdrawls.

Assume deposits include salary ($400/month) and allowance ($400)

Withdrawls depend on rent ($400/month), utilities ($100/month), and entertainment ($200/month)

Start with an initial balance of $1000.  What is the balance after 10 years (120 months)?  Graph the result and describe the function.

Now create a converter for interest that is dependent upon your balance and interest rate.

Assuming an interest rate of 5% per year (compounded monthly), what it the balance after 10 years?  Graph the result and describe the function. Why is the shape of the curve different from the previous run of the model?
