Answer:
$1,539 million
Explanation:
The accounting principle states that assets must equal liabilities plus owner's equity. If assets increased by $534 million and liabilities increased by $261 million, the amount by which equity increased is:
[tex]E_i = A_i - L_i\\E_i= \$534 - \$261\\E_i=\$273\ million[/tex]
If the initial equity was $1,266 million, JetBlue's equity at the end of the year was:
[tex]E = \$1,266+\$273\\E=\$1,539\ million[/tex]
