Answer:

y = 0.5x

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 1, y = 0.5

k = $\frac{y}{x}$ = $\frac{0.5}{1}$ = 0.5

y = 0.5x ← equation of variation

➷ T $\boxed{4}$ B $\boxed{24}$

✽ Ok, so B is the number of boys and T is the number of teachers.

➷ $t \div ( B + 18) = \frac{2}{21}$

$\frac{B}{18} = \frac{4}{3}$

✽ Then solve the second equation for B.

➷ $B = 24$

✽ Plug into the first equation to find T.

➷ $T \div (24 + 18) = \frac{2}{21}$

$T = 4$
