Maria, Adam and Tom have formed a partnership. The total investment was $400000. Maria owns 35.4% and Adam owns 28.8% of the partnership. How much did Tom invest?

Tom invested 35.8% of$400000 = $143,200

Step-by-step explanation:

100%-35.4%-28.8% = 35.8%

Multiply 35.8 % (0.358) x $400,000 = $143,200.

Check work:

400,000 x 35.4% = $141,600

400,000x 28.8% = $115,200

Add all of the totals together:

141,600 + 115,200 + 143,200 = $400,000
