Larry needs to score 33 points in the last game to have an average of 25 PPG.
To find the answer, we can solve the equation:
[tex]\frac{(4)23+p}{5}=25[/tex]
(where p is how many points he needs to score in the last game)
To find the mean of a group of numbers, you add them all up and divide the total by the number of numbers there are. Since Larry averaged 23 PPG in 4 games, we can multiply 23 by 4 to get the total of the first 4 games from the data. Then, we find p, which we will add to get our final total. Then, you divide by the 5 games.
[tex]\frac{(4)23+p}{5}=25[/tex]
[tex]\frac{92+p}{5}=25[/tex]
[tex]{92+p}=125[/tex]
[tex]p=33[/tex]
First, I simplified 4 x 23 to get 92. Then, I multiplied each side by 5 to get rid of the denominator. Finally, I subtracted 92 from each side to isolate p, and found that p = 33.
