Problem-Solving Strategies: Make A Table



Solve the following problem by making a table.



As a first step in determining a studentís grade point average, the points for each course letter grade are multiplied by the credit value of the course to determine the studentís total points.


The points for each letter grade are as follows:


†††††††††††††††††††††††††††† Letter Grade††††††††††††††††† †††† Points


††††††††††††††††††††††††††††††††††††† A††††††††††††††††††††††††††††††††††† 4

††††††††††††††††††††††††††††††††††††† B††††††††††††††††††††††††††††††††††† 3

If each of Stephanieís five courses is worth one credit each and she has a total of 13 points, what combinations of letter grades could she have?
