The multiplicative identity shows us that any time you multiply something by the number 1, the result would be what you started with.
Ex: 1(m) or 1 x m.
The reason for thusbis that when you are multiplying you are representing groups of something, so 1 group of anything or m, would just be that anything or m in this case!

The amount of net profit the store makes on each container is given by 1.67-0.83 (the amount it is sold for subtracted by the amount it costs the store), which is $0.84 per container. They sell 470 containers, so the net profit at this point is 470(0.84) = $394.80.
However, since the distributor is giving the store a $0.50 refund on all every container under 500 that the store sells, the store gets additional money back:
500-470 = 30 containers not sold
30(0.50) = 15
So the total profit is $394.80 + 15 = $409.80.
1 kilometer = 1000 meters
1 x 5 kilometers = 1000 x 5 meters
5 kilometers = 5000 meters

To answer this question, you should draw a picture of a large rectangle with labels 15 ft by 20 ft.
Inside the large rectangle, draw another rectangle (the carpet) with dimensions 9 ft by 12 ft.
When you do this, you will see that you will have 3 feet of space on both sides of the longer wall (15 - 9 = 6; 6/2 = 3 feet).
On the shorter wall, you will have 4 feet of space (20 - 12 = 8; 8/2 = 4 feet).
You will have room for your couch on the shorter wall without touching the carpet.
