four students spent $12 on school lunch .at this rate,find the amount 10 students would spend on the same school lunch

Answers

Answer 1

Answer: In order to solve this, we need to figure out how much ONE student spends.
$(12dollars)/(4students) = 3$ dollars per student.

If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
$10students* (3dollars)/(student) = 30dollars$

Answer 2

Answer: 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
