Answer: debit to Stock Investments for $55,080.
Explanation:
As this is an investment in another company, it will count as an asset which means that when it increases, the account will have to be debited. It will therefore be debited for $55,080 to show the investment.
Cash will decrease by the same amount which means that it will have to be credited because assets are credited when they decrease.
