What to Study
Sections 2.1, 2.2, and 2.3.
• Solving Equations
• Fractional Equations
• Decimal Equations
• Word Problems
The tests consists of 6 equations to solve, and 6 word problems to set up and solve. There is also some extra credit. The word problems have been organized into three sets (A, B, C), from easiest to hardest. The directions of each set will tell you how many word problems to work in that set. For example, in Set A, there are four problems, and you are required to set up and solve three of them.
Formula Bank
I have also included the following Formula Bank on the test.
• Regular Pay + Overtime Pay = Total Pay
• Principal × Rate = Interest
• Original Price – Discount = Sale Price
• Cost + Profit (of Cost) = Selling Price
• Cost + Profit (of Selling Price) = Selling Price
