4students spent $12 on school lunch. at this rate, find the amount 10 students would spend on the same school lunch.

You are suppose to put 4/10= ?/12 and find the question mark by cross mulitplying or scaling you should have took that lesson in your cross products and scaling 
 
HOPE THIS HELP:}

If 4 students spend $12 then 2 students spend $6. 4x2 = 8 students. Which is $24. So add the amount of 8 students and 2
