# Understanding Equations

Required Resource-Read/review the following resources for this activity:

• Textbook (Pre-Algebra): Chapter 2, 3, 4, 8
• Minimum of 1 outside scholarly source (in addition to the textbook)

Instructions-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.

For the initial post, find another formula that you use in your daily life, and explain the meaning behind it.

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.

Writing Requirements

• Minimum of 2 sources cited (assigned readings and an outside scholarly source)
• APA format for in-text citations and list of references
