George and Mary are doing their grocery shopping for the week, and they have agreed that they cannot spend more than $130 in this trip. They have a list of items that they agree are essential purchases and they will buy additional items depending upon what they can afford.
Using what you have learned in this section, explain a strategy they can use to estimate how much money they will have left after they have made their essential purchases. Give your own estimate and then make a list of the extra purchases you would suggest they make that still stay within their budget.
