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 = 48 when p = 8, we can find k by substituting these values into the equation: 48 = k*8, which gives k = 6. To find m when p = 7, substitute p = 7 into the equation m = 6p, giving m = 6*7 = 42.
