Answer:
since Orbit's investment represents a significant influence (more than 20%) on State, we have to use the equity method for accounting for investments in other companies.
the journal entry to record the initial investment:
January 5, 2019, investment in State​ Investments, Inc.
Dr Investment in State​ Investments, Inc., 760,000
  Cr Cash 760,000
When we use the equity method, cash dividends decrease the carrying value of our investments:
June 14, 2019, cash dividend received from State Investments, Inc.
Dr Cash 280,000
  Cr Investment in State​ Investments, Inc., 280,000
