Tammy invested 35.8% into the partnership

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%
