Tammy invested $143,200 or 35.8%

Step-by-step explanation:

Enid, Eve and Tammy have formed a partnership.

The total investment in that partnership was = $400,000

Enid owns 35.4% and Eve owns 28.8% of the partnership.

Enid invested = 35.4% of 400,000

                       = 0.354 × 400,000

                       = $141,600

Eve invested = 28.8% of 400,000

                      = 0.288 × 400,000

                      = $115,200

Tammy invested in that partnership = Total investment - (investment of Enid + investment of Eve)

Tammy's investment = 100% - ( 35.4% + 28.8% ) = 35.8%

                     = 400,000 - (141,600+115,200)

                     = 400,000 - 256,800

                     = $143,200

Tammy invested $143,200 or 35.8%
