Here are the steps you should take to complete this Assignment:

$1)$ Think of a first$-$order feedback system. Make sure you determine the causal variables and which are stocks, flows, and just variables. Do not get too fancy here $-$ just a first$-$order feedback system, which is similar in scope to the Savings Account Exercise.

$2)$ Using Vensim, build the model. This means the model sketch, the variables, all of the parameters needed for it to run correctly. Don$$t forget to set the time frame, units, and initial value

of the stock. Refer back to the savings account exercise if you need to remember how to do this.

$3)$ Your model must run correctly for full credit.

$4)$ Submit your Model File $(.$mdl or $.$mdlx file$),$ not a picture, prior to the due date in Canvas.
