Where P is price in naira and Q is quantity.
Find Q when P = 20 naira.
The correct answer is C. 28 bags
The demand for beans in bags is given by the function Q - 36 + 0.4P = 0, where P is the price in naira and Q is the quantity demanded.
We need to find Q when P = 20 naira.
To find Q, we can substitute P = 20 into the demand function and solve for Q:
Q - 36 + 0.4(20) = 0
Q - 36 + 8 = 0
Q - 28 = 0
Q = 28
Therefore, when the price of beans in bags is 20 naira, the quantity demanded is 28 bags.
So the correct answer is C. 28 bags
