Using the direct variation formula, we can write the equation as:
y = kx
where k is the constant of variation.
To find the value of k, we can substitute the given values:
24 = k * 8
Solving for k, we get:
k = 24/8 = 3
Now, we can use the value of k to find the value of y when x = 10:
y = 3 * 10 = 30
Therefore, the value of y when x = 10 is 30.
