Problem-Solving Strategies: Make A Table

 

 

Solve the following problem by making a table.

 

 

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

 

The points for each letter grade are as follows:

 

                             Letter Grade                       Points

 

                                      A                                    4

                                      B                                    3

                                      C                                    2

                                      D                                   1

                                      F                                    0

 

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