Help please grade 3 maths problem

Number who walk to school = 16

Step-by-step explanation:

If there are 42 students, and 23 girls, there must be 19 boys since 19 + 23 = 42.

If ten girls walk to school, then there are 13 girls left to sort.

Since 7 of the 11 students on the bus are boys, that means 4 girls ride the bus too, so we have 9 girls left.

All we have left is cycling, so 9 girls must cycle to school.

Now, all we have to do is add 6 and 7 since 6 boys bike and 7 boys ride the bus. That equals 13 boys who do not walk.

19 boys total - 13 boys who dont walk = 6 boys that walk.

6 + 10 = 16

Number who walk to school = 16

she will most likely have 33
