1. Objective: To solve multi-step equations.
Do Now:
A factory manager is packing engine components into wooden crates to be shipped on a small truck. The truck is designed to hold sixteen crates and will safely carry a 1200 lb cargo. Each crate weighs 12 lbs empty. How much weight should the manager instruct the workers to put in each crate in order to get the shipment weight as close as possible to 1200 lbs? Create an equation and solve.

3. Important Terms
Since the Do Now equation requires more than one step to solve, it is called a multi-step equation. To solve this equation, we must undo each operation by working backwards.

8. Important Terms
Consecutive integers are integers in counting order, such as 4, 5, and 6 or n, n+1, and n+2. Counting by two will result in consecutive even integers if the starting integer n is even and consecutive odd integers if the starting integer n is odd. Number theory is the study of numbers and the relationship between them.
