four students spent $12 on school lunch .at this rate,find the amount 10 students would spend on the same school lunch
In order to solve this, we need to figure out how much ONE student spends.
\(\frac{12dollars}{4students} = 3\) dollars per student.
If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
\(10students* \frac{3dollars}{student} = 30dollars\)
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
