Quizplus · Accepted Answer

Since y varies directly with x, we can write y = kx, where k is the constant of variation. To find k, we can substitute the given values of y and x, giving us:
8.4 = k(24)
Solving for k, we get:
k = 8.4/24
k = 0.35
Therefore, the constant of variation is 0.35 or 0.65 if rounded to one decimal place, which is answer choice B.
