Question 35149
Please explain to me how to answer this question on my graphing calculator.......A company finds that the cost C to produce x items is C=560+12x, while the revenue is R=20.7.  Find the break even point.  Provide 2 tables to justify your answer.

Graph the equation y=560+12x
Graph the equation y=20.7
Graph both of these on the same screen.
If you have a TI 8X calculator go to 
2nd CALC
Select "Intersect"
Hit the enter button slowly 3 times to see
the point of intersection.  Notice the 
x value.
Now go to 2nd  Table Set
Enter the x value of the intersection point
Then go to 2nd Table.
Notice the values under the columns headed Y1, Y2
Notice the x value where the y values are the same.
Cheers,
