7-8 Simple and Compound Interest – We learned to solve simple-interest problems. Then we learned that the rate for simple interest is the annual percentage rate (APR), or the percent used to calculate interest that is paid in one year. We learned that in simple interest calculations using the formula I = prt, t represents time as a fraction of a year.

7-7 Transforming formulas – We learned to solve a formula for a given variable. Then we learned to use formulas to solve problems. Next, we learned to use transforming a formula for real-world problem solving.
7-5 Solving Equations with Variables on Both Sides – We learned to solve equations and problems with variables and constants on both sides of the equal sign. We learned to get the variable terms on one side of the equation using inverse operations.
7-4 Write an Equation – We learned to write an equation to solve a problem. Then we learned that when you write the words to suggest an equation, you are stating a relationship in a clear unambiguous way. You are also organizing what you know and what you want to find into a mathematical sentence. Next we learned to represent what you want to find with a variable.

7-3 Multi-Step Equations with Fractions and Decimals – We learned to solve multi-step equations with decimals by combining like terms on both sides of an algebraic equation. Then we learned to distribute the LCM (Least Common Multiple) throughout equations to remove fractions.
