The total for 4 games is 4*23=92. To have an average of 25, the total PPG would be 100, so the last game has to pick up 8 points, and 8+23=31. 3*23+31=100 which is an average of 25PPG.

Multiply 5 by 25 to find the total points Larry needs to score in 5 games. 5 × 25 = 125.

Then find the total points Larry scored in the first 4 games. 4 × 23 = 92.Subtract to find the number of points Larry needs to score in the fifth game. 125 – 92 = 33 points.Larry needs to score 33 points in the last game.
