If a 20 percent increase in the price of red bull energy drinks results in a decrease in the quantity demanded of 25 percent, demand for red bull is in this range.
a. inelastic
b. elastic
c. vertical
d. unit elastic

option B

Explanation:

The correct answer is option B  

In economics, the elasticity demand is how sensitive the demand for a good is to change with other economic variables. Elastic demand is one in which elasticity is greater than 1 means high responsiveness to changes in price.

Inelastic demand is one in which the elasticity is less than one in which means low responsiveness to change in price.

so, Red Bull is Elastic range

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
