A store employee notices that microscopes that cost her store $68 are being sold for $204. What is the mark-up, as a percentage?

news channels,news papers,and the internet

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

look at the picture i have filled out a table for it. hope this .
