Answer :

In order to solve this, we need to figure out how much ONE student spends.
[tex] \frac{12dollars}{4students} = 3 [/tex] dollars per student.

If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
[tex]10students* \frac{3dollars}{student} = 30dollars[/tex]
ok so you will multiply 12 times 10 or you could add 12 + 12+12+12+12+12+12+12+12+12 add them up and it will be $120
