Respuesta :

You would do 12÷4 to find out how much each person would spend which would be $3.00 each so do 3x10 which is 30 so... 10 students would have spent $30.00 on The same school lunch.
I'm assuming you mean 10 students altogether...

12 / 4 = 3

$3 are spent by each student.

10 students would spend $30 on the same lunch if each spends $3.

Hope I was able to help :)
