Own price elasticity of demand for vibranium has been estimated at 0.8. As a result a
mining accident, quantity decreases 3%. What is the predicted percent change in
price?
In calculating changes, you may be tempted to use midpoints. Don't. Trust me.
Round the percent change to two decimal places and do not enter the % sign. If
you predict a 10.125% decrease in price, enter -10.13.)
Correct Answer
3.75
