If y varies directly as the square of x and y=950 when x=25, find y when x= 20.

Thank you for the opportunity to help you with your question!

y=k.x^2

950 = k(25)^2

950 = k.625

k = 950/625

y = k(20)^2

   = 950/625 . (400)

  = 608

Please let me know if you need any clarification. I'm always happy to answer your questions.
