b. 30

Since y varies directly with x, this means that y = kx, where k is a constant of variation. To find the value of k, we can plug the values of y = 24 and x = 8 into the equation:

24 = k * 8
k = 3

Now that we have the value of k, we can find the value of y when x = 10:

y = 3 * 10
y = 30

Therefore, the value of y when x = 10 is 30.
