Answer:
Tammy invested $143,200 or 35.8%
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%
