__Understanding Equations (graded)__

Being successful in mathematics requires understanding as opposed to simple memorization. For example, the formula to find the perimeter of a rectangle is P = 2L + 2W (where L is length and W is width). Memorizing the formula could be helpful, but if we understand that the perimeter is the distance around the rectangle, we are able to construct the formula and apply it to real-world situations correctly.

Find another formula that you use in your daily life, and explain the meaning behind it. Then, look at one of your classmate’s formulas and see if you agree with your classmate’s interpretation of its meaning.

For example, the formula to calculate sales tax on a purchase is sales tax = 0.0825x. The coefficient, 0.0825, is the current tax rate of 8.25%. The variable, x, is the amount of your purchase.
