50 points! if you can solve it, then you have more than just a brain! (4 answer question)! there are 10 total people in the regular classroom. each student has one notebook and one pencil. if there are 3 boys in the classroom, how much total supplies the boys have? how many girls are there in the class? how much total supplies do the girls have? how much total supplies are there in all?

3boys=6 supplies (1 notebook and one pencil per student)

if there are a total of 10 people:
10-3-1= 6 girls
girls=12 supplies
total supplies=18 supplies

Assuming there is no teacher:
1.) Since we know that each boy gets one notebook and one pencil, you can calculate total supplies using multiplication and them addition.

Notebook: 1×3 = 3
Pencil: 1×3 = 3
Total: 3+3 = 6

2.) Since we know there are 10 total people and three are guys, we can find how mnay girls there are using subtraction.

10 - 3 = 7 girls

3.) We can find their supplies using the same procedure as the boys just with 7 girls instead.

Notebook: 1×7 = 7
Pencil: 1×7 = 7
Total: 7+7 = 14

4.) To find the entire total, we just add the boys and the girls totals.

6 + 14 = 20

If there is a teacher, then there are 9 students in which 6 are girls.

6× 1 = 6
6 × 1 = 6
6 + 6 = 12 total for girls
and 12 + 6 = 18 total for the class.

I hope this helps!
