At the county fair, 210 snow cones were sold for a total of $540. Large snow cones (x) cost $3.00 each and small snow cones (y) cost $2.00 each. Which equations below could be used to model this system of equations? Select all that apply.

3x + 2y = 540

x + y = 210

Step-by-step explanation:

Giving the following information:

At the county fair, 210 snow cones were sold for a total of $540. Large snow cones (x) cost $3.00 each and small snow cones (y) cost $2.00 each.

We can establish the following system of equations:

x= number of large snow cones sold

y= number of small snow cones sold

3*x + 2*y = 540

x + y = 210

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
