A watermelon that weighed 12 pounds cost $5.76. What was the cost per ounce of the watermelon?

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

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 )
