There are 42 students in a class.
Each student walks to school or cycles to school or gets the bus to school.
There are 23 girls in the class.
10 of the girls walk to school.
6 of the boys cycle to school.
7 of the 11 students who get the bus to school are boys.
Find the number of these students who walk to school.
Your final line must say, Number who walk to school = ...

16

Step-by-step explanation:

Out of 42 students, since 23 are girls then boys will be 42-23=19 boys

Boys who either cycle or use bus are 6+7=13

Therefore, boys who walk will be 19-13=6

Girls who walk are given as 10

Total students who walk=10+6=16

Girls who get to bus are 11-7=4

Girls who cycle will be 23-(10+4)=9

Boys who cycle are 6

Total students who cycle=6+9=15

Boys who cycle are 7

Girls who use bus are 11-7=4

Total students using bus are 7+4=11

the answer is y = 11.54
