<u>Using mental math to find the slope of the line:</u>
If you think about the formula, then you set up the points in your head, you will notice that the first point is on top of the second point. And that way makes it easy to simplify. All you would need to do is subtract down in your head: For example:
(0, 0)
(4, 8)
As you can see, the first point is on top of the other, and that way you can just subtract from bottom to top. If you do it that way, it is set up (Remember, you would do this all in your head)
To solve for the materials quantity variance, we have the formula below:
Materials Quantity Variance = (Actual Quantity Used * Standard Rate) - (Standard Quantity Allowed * Standard Rate)
The solution is shown below:
Materials Quantity Variance = ($9.20 - $9.00)*3400
Materials Quantity Variance = $680
The answer is $680.
