Question

If elasticity is given by, $E_{x,y} = \frac{\%\Delta X}{\%\Delta Y}$, then elasticity is negative when: a decrease in X has no effect on Y. a decrease in Y produces an increase in X. an increase in X produces an increase in Y. an increase in Y produces a decrease in X.

          If elasticity is given by, $E_{x,y} = \frac{\%\Delta X}{\%\Delta Y}$, then elasticity is negative when:

a decrease in X has no effect on Y.
a decrease in Y produces an increase in X.
an increase in X produces an increase in Y.
an increase in Y produces a decrease in X.

If elasticity is given by, Ex,y = (%Δ X)/(%Δ Y), then elasticity is negative when:

a decrease in X has no effect on Y.
a decrease in Y produces an increase in X.
an increase in X produces an increase in Y.
an increase in Y produces a decrease in X.
