y = 9x

y = 9x means each box of the new brand is $9. 

So the old brand is $2 per box more. I know you

the 9 represents the price so he is saving 2 dollars on the new brand he gets per box.

if he buys 6 boxes of the $9 box he will spend $54

if he buys 6 boxes of the $11 box he will spend $66

So with six boxes he saves 12 dollars
