your subtract how much you started with by what is left. After that, you divide that number by how much you bought.
If we look at his calculations
2((9)(20) is the front an back rectangle
2((9)(34)) is the side rectangles
(34)(20) is the bottom
2(1/2(20(24)) is te front and top triangles
and the last one assumes that they are triangles which is incorrect

Ok so this person was paid $422.75 this week for working one week. $42.75 though, was added onto her normal paycheck because she worked overtime. So we subtract the $42.75 from the $422.75 to get $380. So if she made that normal money by working for 40 hours we need to find how much money she makes in one hour. SO we just do 380/40 to get $9.50 per hour
