Question

Constant of the variation?

Answer 1

Constant of variation is `3`.

Explanation:

Let the rate be `$x` per kilogram. Let amount of candies one can have be `y` kilogram.

For `$3` one can get `3/x` kilogram of candies. Hence `y=3/x` or `xy=3`

Hence at `0.50` per kilogram, one can get `3/0.50=6` kilogram.

When rate goes to `$1.00` per kilogram, one can get `3/1=3` kilogram

Observe that as `x` increases `y` decreases but `xy` remains constant at `3`.

Hence relation is inverse and constant of variation is `3`.
