Stuck on this question. don’t know how to start it?

First you have to figure out how much the down payment will be. So you have to find what 20% of $160,000 is. Then you have to find out how much you can save per year. To do this, find what 10% of $41,000 is. Then you divide the down payment by your yearly savings to find how many years it would take to save the money required.
