It's y=kx. But 'k' is any constant. So my 'k' can easily be 1/(your k). The key is that when 'x' or 'y' increases by some factor, the other one also increases, by some constant multiple of the same factor. If so, then they're proportional.
Hey, I'm assuming you mean five refrigerators every eight hours. So . . .
1250 divide by 5. Which gives you 250.
Then take that 250 and multiply it by 8, and you have 2000.
So it would take 2000 hrs for a factory, that can produce 5 refrigerators every eight hours to, produce 1250 refrigerators.
