, take this as equation 1.

It is also given they both earned $115.56 out of which snickers sold for $1.50 each and fruit juice sold for $1.26 each. So,

, take this as equation 2.

Step 2:

Now we solve these equations.

Equation 1 can also be, , take this as equation 3.

Substitute equation 3 in 2,

Taking the known values to the right and keeping the unknown x values on the right, we get

Substitute this is equation 1,

So Mr. Sanchez’s class sold 51 snickers and Mr. Kelly’s class sold 31 bottles of fruit juice.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
