high school class is putting together a newsletter. The cost of design and colour copies is $200 plus $0.75 per copy. The class plans to sell the newsletter for $1.25. Solve the system of equations using the desmos application and write the point of intersection.

Answer 1

To solve the system of equations using the Desmos application, we need to first set up the equations.

Let x represent the number of copies of the newsletter sold.

The cost of design and colour copies is $200 plus $0.75 per copy, so the cost equation is:
Cost = 200 + 0.75x

The class plans to sell the newsletter for $1.25, so the revenue equation is:
Revenue = 1.25x

To find the point of intersection, we need to set the cost equal to the revenue and solve for x:
200 + 0.75x = 1.25x

Now we can graph these two equations on Desmos to find the point of intersection.
