• 17. Points Scored in a Basketball Game

The Dallas Mavericks hosted the Oklahoma City Thunder in game 1 of the Western Conference finals on May 17, 2011. The shot chart shows the final field goal data for Kevin Durant and Dirk Nowitzki, the top scorers on each team. Nowitzki had one of the most efficient playoff games in NBA history. Not only did he shoot a high percentage from the floor, he also made 24 out of 24 free throws (an NBA playoff record). How many points did Nowitzki score? (See Example 5 and Example 6.)

• Worked-Out Solution

Nowitzki made 24 free throws and 12 field goals. In basketball, a free throw is worth one point. Field goals made inside the three-point line are worth two points. Field goals made outside the three-point line are worth three points. From the graph, you can see that all of Nowitzki's field goals were made inside the three-point line, so all 12 field goals are worth 2 points. To calculate the number of points that Nowitzki scored, add the points for the 24 free throws and the 12 field goals.

So, Nowitzki scored 48 points.
