This is another proportion question that I am having trouble with. Please help me solve it a.s.a.p, it would be greatly appreciated!

You and your two friends, Jim and Susan have decided to open a business. You contribute \$24 000 to the start-up, while Jim and Susan contribute \$14 750 and \$11 200 respectively. A few months later, due to bad economic conditions, the business needs an additional investment of \$20 000 from the partners. How much money should each person contribute to maintain the investment in the original ratio

The portions of the investments started as follows:

you= 24,000

Jim= 14,740

Susan = 11,200

The total investment = 24,000+14,750+11,200= 49,950

Now we will determine the ratio for each one.

You = 24,000/ 49,950

Jim = 14,740/49950

Susan = 11200/49950

Now we will need to add 20,000 to the total investment and determine how much each should contribute based of the same ratios.

Total investment now = 49950 + 20000 = 69,950

Now we will calculate total investment for each:

You = x/69950 = 24000/49950

==> x = (24000*69950)/49950 = 33,610

Jim = y/69950 = 14750/49950

==> y= (69950*14750)/49950 = 20,656

Susan = z/69950 = 11200/49950

==> z = (11200*69950)/49950 = 15,684

Now we will subtract the initial investment from each to find how much each should contribute:

==> You = 33610 - 24000 = 9610

==> Jim = 20,656 -14750 = 5906

==> Susan = 15684 -11200 = 4484

Now to check the answer , the total additional investment should equal 20000

==> 9610 + 5906 + 4484 = 20000

The amount each should contribute is:

you = \$9610

Jim = \$5906

Susan = \$4484
