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.
Suppose y varies directly with x, and y = 24 when x = 8. What is the value of y when x = 10?
