The number of representatives N that each state has varies directly as the number of people P living in the state. If New York, with 19,254,630 residents, has 29 representatives, how many representatives does Colorado, with the population of 4,665,177, have?
Thanks in advance for all of your help math GODS:cool:
Do you know the "general formula" for direct variation?
y = kx
I mention this because of the question you asked in the heading to your post.......
k is known as the constant of variation.
For your problem, suppose we let x = the population of the state or P, and let y = the number of representatives which your problem calls N.
Then we could write the variation equation as
N = k*P
You are told that New York, with a population of 19,254,630, has 29 representatives. So, when P = 19,254,630, N = 29. Substitute into the variation equation:
N = k*P
29 = k * 19254630
You should be able to solve now for k, the constant of variation, and then write the variation equation using the appropriate value of k.
And once you have this variation equation completed, you should be able to USE it to find the number of representatives for any state if you know the population of that state....specifically, you can complete your exercise by finding the number of representatives for the state of Colorado.
