I think is A! Im not sure tell me if it’s right
62%
of 25
'of' means multiplication.

Convert 62% to a decimal, divide it by 100(since percentages are parts of 100):
62/100 = 0.62

Multiply:
There are 4 quarts in a gallon, so multiply 20 x 4 to get 80.
The aquarium can hold 80 quarts.
Hope I helped!
Solution
The counselor has 12 electives courses (e.g. art, band, PE, etc.) to choose from and must select 2 ordered classes for each 6th grade student.
Let S be the sample space.
Then, n(S) = 12C2 = (12 x 11) ÷ (2 x 1 ) = 132 ÷ 2 = 66

Sixty six (66) ways can the counselor arrange the last 2 periods of the day for the 6th grade students
