Real world, using percents
Our project was to pick a job and baised off our sallory would create a budget for everything. Then we ate at a resturant and had to stay in budget. We had to buy a car and stay in budget and buy 5 things and the of the money goes into our car.
I have learned that if you have a job and your spending money you need budgets. It keeps you from wasting all your money. So I think budgets are very helpful. It evens out the spending of your money.
