Answer:

[tex]\huge\boxed{\sf y = 30}[/tex]

Step-by-step explanation:

Given that:

y ∝ x

Turning proportionality into equality by putting the constant 'k'

y = kx ---------------------(1)

We know that y = 24, when x = 8

24 = k(8)

Divide both sides by 8

24 / 8 = k

3 = k

OR

k = 3

Now, Finding y when x = 10

Put x = 10 and k = 3 in Eq. (1)

y = (3)(10)

y = 30

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!
