Suppose the market for dairy milk experiences the following event: The price of nut based milk (a substitute for diary milk) increases. The effect on equilibrium will be:

equilibrium price and quantity of diary milk will increase

Explanation:

A substitute good is a good that can be used in place of another good.

If the price of nut based milk, a substitute for diary milk increases, nut based milk becomes more expensive for consumers and as a result consumers would increase their demand for diary milk. This would lead to an outward shift of the demand curve and as a result, equilibrium price and quantity of diary milk will increase

Please check the attached image for a graphical representation

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
