Follow up to the other tough one. Same formula for it will be expressed the same. It asks that given that city C (population 702,000) is 200 hundred miles from City D (population 321,000) what is the average number of daily phone calls between city C and city D?

Question

anonymous · Answer

$$C=\frac{ kP _{1}P _{2} }{ d ^{2} }$$ for the formula again

anonymous · Answer

So now that you have k = 0.03, you can plug in the values to solve for C:
k = 0.03
P1 = 702,000
P2 = 321,000
d = 200

I get 169006.5 
 for an answer. Since I am to round it to the nearest whole number it would then be 169006 correct?

anonymous · Answer

Whenever you have a decimal >= .5, I would suggest rounding up

anonymous · Answer

You are so right. I can't believe I did that. :-) Thanks for pointing it out.
Do you think I have the number right for the equation at
169007 then?

Anyone want to double check for me?
