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.
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.
