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

$30

Step-by-step explanation:

if four students spent $12

then 10 students will spend how much..?

4=12

10=x ( u choose any letter for finding the

unknown quantity )

u cross multiplication, u get

4/4x =120/4

then x = 30 .

so 10 students would spend $30.
