Since y varies directly with x, we can write the equation as y = kx, where k is the constant of variation.
We are given that y = 24 when x = 8. Plugging these values into the equation, we get 24 = k * 8. Solving for k, we find that k = 3.
Now we can use the equation y = kx to find the value of y when x = 10. Plugging in x = 10 and k = 3, we get y = 3 * 10 = 30.
Therefore, the value of y when x = 10 is 30.
