Emmy Mejia · Answer 1

fifth graders = 93 shirts

sixth graders = 156 shirts

teachers = 51 shirts

Step-by-step explanation:

31% of 300 is 93

52% of 300 is 156

156+93 = 249

300-249 = 51

Smarty · Answer 2

Step-by-step explanation:

The total number of shirts that the school club sold is 300.

31% were sold to fifth graders. This means that the number of shirts that were sold to fifth graders is

31/100 * 300 = 0.31 * 300 = 93

52% were sold to sixth graders. This means that the number of shirts that were sold to sixth graders is

52/100 * 300 = 0.52 * 300 = 156

The total number of shirts sold to fifth graders and sixth graders is

93 + 156 = 249

The number of shirts sold to teachers is

300 - 249 = 51
