So we get N=2F , N=4/3C and N=4A through those relations we can put an equation with only Californian zips as variable 4/3C + 1/3C + C + 2/3C=250 therefore C=75 then the ratio would be equal to 150000/4/75 =500 hope it helps :p

a) 500 b) 750 c) 1,000 d) 1,250 e) 1,500 Let's put everything in number of Northeastern zip codes since all those relations are given. Since N = 2F, no of Florida zip codes (F) will be N/2. Since N = 4A, no of Arizona zip codes (A) will be N/4 Since N = (4/3)C, no of California zip codes (C) will be 3N/4 N + N/2 + N/4 + 3N/4 = 5N/2 = 250 N = 100 C = 3N/4 = 75 No of orders is 25% of 150,000 = 37,500 So required ratio = 37,500/75 = 500

I wanted to translate everything to California zip codes, so we basically have: N=2F=4A=(4/3)C > C( 4/3 + 4/6 + 4/12) = 250 > C*(16+8+4)/12 = 250 And I'm getting a different result than what you're getting for C. Where am I going wrong here?

Where am I going wrong here? You have got everything in terms of C but forgotten to add C. N + F + A + C = 250 C( 4/3 + 4/6 + 4/12) + C = 250 C = 75

Express everything in terms of northeastern zip codes. Let N be the number of zip codes. N + N/2 + N/4 + 3N/4 = 250 which implies that N = 75 25% of 150,000 = 37,500 Therefore the correct answer is A [37,500/75]

a) 500 b) 750 c) 1,000 d) 1,250 e) 1,500 OA:ANumber of Northeastern Zipcodes =\(2\)*Number of Florida Zipcodes =\(4\)*Number of Arizona Zipcodes=\(\frac{4}{3}\)*Number of California Zipcodes Number of Northeastern Zipcodes + Number of Florida Zipcodes + Number of Arizona Zipcodes + Number of California Zipcodes \(= 250\) \(\frac{4}{3}\) Number of California Zipcodes+\(\frac{2}{3}\) Number of California Zipcodes+\(\frac{1}{3}\) Number of California Zipcodes+ Number of California Zipcodes \(= 250\) \(\frac{4+2+1+3}{3}\)Number of California Zipcodes \(= 250\) Number of California Zipcodes\(= 250* \frac{3}{10} = 75\) Number of Orders \(=\frac{25}{100}*150,000\) Ratio of the number of orders to the number of California's zip codes \(=\frac{ \frac{25}{100}*150,000}{75}= 500\)
