The effect of the decrease in the price of the guitars illustrates an elastic demand.
The first step is to determine the percentage change in the price of the guitars.
Percentage change in price = (2499 / 2699) - 1 = -0.074 = -7.4%
Now, determine the price elasticity of demand =30 / -7.4% = -4.1
The coefficient of elasticity is greater than 1 in absolute terms, thus the demand is elastic.
