Country A produces about three times the amount of diamonds in carats produced in country B. If the total produced in both countries is 4,000,000 carats, find the amount produced in each country

You could choose suitable variables to represent the output of each country, say A for country A and B for country B. You are given two ways to relate these variables...can you identify the relations and state them mathematically?
Hello marukai47.
Let A be the number of carats produced by A country and B be number of carats produced by B country, since A country produces three times of diamonds than B country, you can let, and you also know that the sum of number of carats produced by both countries is 4,000,000, so you've got second equation,
. You can solve this system of equations by substituting 3B instead of A in the second equation and you will get
->
->
->
. Since number of carats produced by B country is 1,000,000 and you know that A country produces 3B carats, you multiply 1,000,000 by 3 and you get that
. I hope this helped.
Wrong answer....
Can you show how this is wrong?
When I type the answer into MathXL it says wrong. I did it twice and now have one more try at getting it right
I finally got it right. I was accidentally using a decimal instead of a comma
Suppose country A produces 5 times what country B produces and together they produce 3 million carets. What would the output of each country be?
Correct. And I appreciate the fact that you gave the OP more than 24 hours to respond! :)
Do you mean how would one algebraically solve this problem?
