Question

Felipe has scored 16, 23,25, and 28 points in his four basketball games so far. How many points does he net to score in his next game so that his average (mean) is 24 points per game?

Answer 1

Recall that to compute the mean we divide the total number of points over the number of games.

If Felipe wants to have an average of 24 points per game, then

`(16+23+25+28+x)/(5)=24.`

Solving the above equation for x we get:

`\begin{gathered} 92+x=24*5=120, \\ x=120-92=28. \end{gathered}`

Answer: 28.
