Stacy has been baking all weekend for her school's bake sale. She used 12 ounces of sugar to bake brownies. Then, she used 12 more ounces of sugar to bake cupcakes. Finally, she used 8 ounces of sugar to make frosting for the cupcakes. How many pounds of sugar did she use in all?

2 pounds

Step-by-step explanation: Add up all of the ounces of sugar. 12+12+8=32. There are 16 ounces in one pound, so divide the number of ounces by 16. 32/16=2.

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin
