Math | English | Art | Total
Boys 13 25 11 49
Girls 7 20 6 33
Total 20 45 17 82
1) Let's set a table, based on the given information:
• Since there are 20 students enrolled in Math let's place it into the Total, 20 -13 = 7
,
• 82 students altogether.
,
• 11 boys are in Art , 17 altogethe then 17 -11 = 6 girls
,
• 20+6+7 = 20+13 = 33 girls altogether.
,
• 82 -33 =49 13 +x +11 = 49 x = 49 -24=25
,
• And lastly English: 20 +25 = 45
2) That's our table:
