Replace the question mark! <3 Captured carbon dioxide can be used for different purposes. Food and beverage companies use 4 million metric tons (MMt) of carbon dioxide per year, which is 6% of all captured carbon dioxide. Enhanced oil and natural gas recovery uses 88% of all captured carbon dioxide. Create a formula where x = the amount of carbon dioxide used for enhanced oil and natural gas recovery. Solve for x.

The amount of CO2 used for enhanced oil and natural gas recovery is ? MMt.
