Answer: y = 198
Step-by-step explanation:
y varies directly as x means that:
y = kx
We don't know that constant (k) yet.
Now, we plug in the values of x and y, y=18 when x=12.
y = kx
18 = 12k
k = 18/12
k = 1.5
Now,we rewrite the equation with the value of k.
y = 1.5x
To find y when x = 132
y= 1.5x
y = (1.5 × 132)
y = 198
