$\large\sf\underline{Problem:}$

z varies jointly as x and y if z = 48 when x = 2 and y = 8 find the constant of variation.

$\large{••••••••••••••••••••••••••••••••••••••}$

$\large\sf\underline{Answer:}$

$\huge\tt\purple{\:\:\:\:\:\:\:\:\: B. \:3}$

$\large{••••••••••••••••••••••••••••••••••••••}$

$\large\sf\underline{Solution:}$

$\large\tt{ z = kxy }$

$\large\tt{ 48 = k\: •\: 2\: •\: 8}$

$\large\tt{ \frac{48}{16} = \frac{16k}{16}}$

$\large\tt\purple{ k = 3}$

$\because$ The constant k of variation is 3.
