The correct option is D
Step-by-step explanation:
To determine how many drinks members 21 or over will consume, the correct formula is:
=SUMIF(B2:B35,"25",C2:C35).
This formula uses the SUMIF function in Excel to sum the values in the range C2:C35 (average drink consumptions per night) only if the corresponding values in the range B2:B35 (ages of fraternity members) meet the specified criteria, which is being 21 or over. The correct answer is option D.
The correct option is D
