in a class there are 50 students,15 girls wear glasses 8 do not wear glasses.20 boys don't wear glasses.how many students wore glasses
15 + 8 = 23 girls in the class
50 - 23 = 27 boys
27 - 20 = 7 boys wear glasses
15 + 7 = 22 students wear glasses
To find out how many students in the class wore glasses, we need to add the number of girls who wear glasses and the number of boys who wear glasses.
Given information:
Total number of students = 50
Number of girls wearing glasses = 15
Number of girls not wearing glasses = 15 - 8 = 7
Number of boys not wearing glasses = 20
To find the number of girls wearing glasses, we subtract the number of girls not wearing glasses from the total number of girls:
Number of girls wearing glasses = Total number of girls - Number of girls not wearing glasses
Number of girls wearing glasses = 15 - 7 = 8
Now we can find the number of students wearing glasses by adding the number of girls wearing glasses and the number of boys not wearing glasses:
Number of students wearing glasses = Number of girls wearing glasses + Number of boys not wearing glasses
Number of students wearing glasses = 8 + 20 = 28
Therefore, a total of 28 students in the class wore glasses.
