I think that 10 students will spend $30 on school lunch

Answer:

$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

4x=10*12

4/4x =120/4

then x = 30 .

so 10 students would spend $30.

hope it helped..
