Question

project effect of price change on a complementary good (taking price from real life local market)​

Answer 1

Answer:

If A is a complement to B, an increase in the price of A will result in a negative movement along the demand curve of A and cause the demand curve for B to shift inward; less of each good will be demanded. ... This is in contrast to a substitute good, whose demand decreases when its substitute's price decreases.
