Quizplus · Accepted Answer

Since m varies directly as p, we can write the equation m = kp, where k is the constant of variation. Given m = 63 when p = 9, we can find k by substituting these values into the equation: 63 = k*9, which gives k = 7. To find m when p = 3, substitute p = 3 into the equation m = 7p, giving m = 7*3 = 21.
