Final answer:
If the price of golf clubs increases, the demand for golf lessons will decrease.
Step-by-step explanation:
If golf clubs and golf lessons are complements, then an increase in the price of a golf club would lead to a decrease in the demand for golf lessons.
This is because consumers tend to purchase golf clubs and golf lessons together as they enhance each other's consumption. When the price of a complement good, like a golf club, increases, the quantity demanded decreases. As a result, the demand for the complementary good, golf lessons, also decreases.
For example, if the price of golf clubs rises, people would be less willing or able to purchase golf clubs, and consequently, they may not see the need to take golf lessons anymore.
