3 equations needed

[NitroBlue]

At a track event the concessions sold hamburgers for $3.50 and hot dogs for $2.00. In total, they sold 100 hamburgers and hot dogs combined for $314. Right a system of equations that models the situation. Them solve to etermine the number of hamburgers and hot dogs sold.

let X = Hamburger and Y= hot dogs.

I need 3 equations. Thanks!

let
X = # of Hamburgers sold and Y= # of Hotdogs sold

Money collected from selling hamburgers = # of Hamburgers sold * price of 1 hamburger = X * 3.50 ...............................................eq #1

Why do you need three equations, with only two unknowns?

One equation will say,

In total, they sold 100 hamburgers and hot dogs combined​

and the other will say,

... for $314.​

So what are your equations? Give it a try.
