ATHLETICS of 107 athletes surveyed about what sport they play, some play basketball. of those that play basketball , 48 play bas
aliina [53]

the number of athletes who do not play basketball is 26.

Step-by-step explanation:

<u>DATA:</u>

Athletes surveyed = 107 athletes

<u>Athletes who play basketball</u>

Athletes who play baseball = 48 athletes

Athletes who don't play baseball = 33 athletes

Athletes who play basketball = athletes who play baseball + athletes who don't play baseball

Athletes who play basketball = 48 + 33

Athletes who play basketball = 81

<u>EQUATION:</u>

Total athletes = Athletes who play basketball + Athletes who don't play basketball

107 = 81 + x

x = 107 - 81

x = 26

Therefore,  the number of athletes who do not play basketball is 26.
