I didn't say anything was missing. I asked you to show what you can do, as we ask in our submission guidelines.
They told you this: new value : old value = 4 : 3. Put in the known old value, and solve for the unknown new value. There are several ways you might have been taught to do this, so I want to see what method you try.
It's also possible that the problem could be interpreted differently, so I want to see how you understand its meaning, if you think what I wrote is wrong.
The proportion is new value : old value = 4 : 3 , as I said, which means x/3300 = 4/3. solve that. You appear to be solving 3300/x = 4/3.
Your addition suggests that you are interpreting the "increase" to be by adding 4/3 (like a percent increase), rather than the new value itself being 4/3 of the original. Can you offer evidence that it is to be taken that way (such as an example like this in your textbook)?
I think what you are saying is correct..I was actually assisting a friend who is taking business studies and wouldn't be able to send you an example..
is this correct?
