2. Ask yourself, “what are the variables that we are trying to solve for and what do they represent?”.
3. What is the total cost and what does it represent/how is it created (from the cost of each item)?
4. Is there a certain number of each item that is sold? Add the variables to create the total.

4. 5. Is there a relationship given between the variables
5. Is there a relationship given between the variables? Set up the equations. Get the variables on the left and constant on the right. 6. Use inverse matrices, elimination, substitution, or graphing to solve the equations. 7. Check your solution. Does your solution make sense in the problem?
