    Step-by-step explanation:

    A is the unknown

    "42 students received an A on the second test which is 150% of the students who received an A on the second test"

    150/100 * A=42

    150 * A=42*100

    150A=4200

    A=4200/150

    A=28

    Therefore, the number of students that received an A on the second test is 28.
