Answer: PED = -1.665
The price demand elasticity is relatively elastic because PED is greater than 1..(ignore the minus sign)
Step-by-step explanation:
Using the formula PED = % change in quantity/ % change in price
PED = ((Q1 - Q0)/(Q1 + Q0))/((P1 -P0)/(P1+P0))...EQU 1 where Q1 = 50 is quantity of product at Price P1 =10 and Q0 = 25 is quantity of product at Price P0 = 15 and PED is price of elasticity
Substituting figures into equ1
PED = ((50 - 25)/(50+25)) /((10 -15)/(10+15))
PED = -1.665
