180 - 90 = 90
90 - 19 = 71.
Therefore, the answer is 71
The numeric constant of variation is 100
Step-by-step explanation:
Direct proportion means that increase in one variable cause increase in other variable
Here,
It is given that
y varies directly as x
y∝x
when the proportionality symbol is removed a proportionality constant is introduced

Given that
y = 100 when x = 4
Putting the values
