The shake shack sells large and small shakes. a large shake costs $5, and a small shake costs $3. on sunday, the shake shack had a total revenue of $479. which equation can be used to represent x, the number of small shakes sold and y, the number of large shakes sold?
479x + 479y = 15
4x + 4y = 479
5x + 3y = 479
3x + 5y = 479

3x + 5y = 479

Step-by-step explanation:

As the problem states it, the number of small shakes will be represented by "x" and the number of large shakes will be represented by "y", so we know that the number of each mutiplied by the cost, its equal to the total revenue which is $479, so we just put that into an equation:

3x + 5y=$479

And that´s the equation that can be used to represent that inequality.
