Question 1 (1 point)
A school organized a fundraiser to help a local charity. They sold small and large cookies. The small cookies were $2 each
and the large cookies were $3 each. The group sold 130 cookies and raised $310. How many large cookies did they sell?

For this case we can propose a system of equations:

x: Let the variable that represents the number of small cookies

y: Let the variable that represents the number of large cookies

According to the statement we have:

We multiply the first equation by -2:

We have the following equivalent system:

We add the equations:

We look for the value of the variable "x":

They sold 80 small cookies and 50 large cookies
