Sophia has scored 18,24, and 32 points in her last three basketball games. How many points must she score in the next game so that her four-game average is at least 24 points?

(18 + 24 + 32 + x)/4 >/= 24.

(we use the inequality because her average must be AT LEAST 24 points).

Finding for x

(74 + x) >/= 24 x 4 ==> 74 + x >/= 96

x = 22.

So, Sophia must score at least 22 points in her last game so that her four-game average is at least 24 points.
