he has 40 dollars.
his ticket will cost 12 dollars.
hot dogs cost 2 dollars.
sodas cost 4 dollars.
let x equal the number of hot dogs and let y equal the number of sodas.
your equation becomes 2x + 4y + 12 <= 40.
subtract 12 from both sides of this equation to get 2x + 4y <= 28.
if you let x = 0, then y <= 7
if you let y = 0, then x <= 14
anywhere in between will give you different value.
the first graph shows you just the end points.
the second graph shows you some points in between.
both graphs use the inequality of 2x + 4y <= 28.

Let D = the number of hot dogs he can purchase
Let S = the number of sodas he can purchase



Subtract $12 from both sides:



Divide every term by $2
