2 Lesson Menu Objectives Vocabulary Example 1 Example 2 Example 3 Quick Quiz

3 Objectives To understand the order of operations To practice using expressions to represent specific situations To use flowcharts to build expressions To solve equations using backtracking To use variables to write expressions

4 Vocabulary exponent backtracking flowchart variable

5 Example 1 MONEY Nina has a new job. She spends $2 every day on coffee. Define a variable. Then write a function rule that relates the total amount of money Nina spends on coffee to the number of days at work. Determine the function rule. The amount of money spent depends on the number of days at work. Let x represent the number of days at work.

6 Example 1 Answer: The function rule is 2x. Words$2 for each day VariableLet x represent the number of days. Equation2 ● x Arithmetic Sequences
