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

10
30
80
240
Since y varies directly with x, we can set up the proportion:
y / x = k
where k is the constant of variation.
We can solve for k by substituting the given values:
24 / 8 = k
k = 3
Now, we can find the value of y when x = 10 by substituting into the equation:
y / 10 = 3
y = 30
Therefore, the value of y when x = 10 is 30.
