ExplanationPutting a number for the number of students in the graduating class. When SUPPLYING for a percentage question, it's helpful to use 100.

Number of graduates = 100

Number accepted to college = 80 (80% of 100 OR \(0.80 \times 100 = 80\))

Number of accepted NOT going to college = 8 (10% of 80 OR \(0.10 \times 80 = 8\))

Number of accepted going to college = 72 (80 – 8 = 72)

The percentage of graduates going to college is 72 out of 100, or 72%.

Hence Quantity A is greater.
