example, 40 percent means or 0.40 or .
● Equations of lines 100 5
● Absolute value
● Direct and inverse variation Problem 1: If the sales tax on a $30.00 item is $1.80, what

Newly defined symbols based on commonly used n
● Solution: $1.80 = × $30.00
operations 100
n = 6, so 6% is the sales tax rate.
Geometry and Measurement (25–30%)
Percent Increase / Decrease
● Area and perimeter of a polygon
● Area and circumference of a circle Problem 2: If the price of a computer was decreased from
● Volume of a box, cube, and cylinder $1,000 to $750, by what percent was the price decreased?
● Pythagorean Theorem and special properties of
isosceles, equilateral, and right triangles Solution: The price decrease is $250. The percent decrease

Coordinate geometry is the value of n in the equation = . The value of
● 1, 000 100
● Geometric visualization n is 25, so the price was decreased by 25%.
