Final answer:
A change in one of the determinants of demand or supply can impact Mr. Darp by affecting the supply or demand for smartphones, which can in turn affect the price and profitability of his products.
Step-by-step explanation:
A change in one of the determinants of demand or supply can have an impact on Mr. Darp. Let's say Mr. Darp is a producer of smartphones.
If there is a decrease in the price of a key component used to manufacture smartphones, such as memory chips, then the supply of smartphones would increase.
This would result in Mr. Darp being able to offer smartphones at a lower price, which may lead to increased demand for his products.On the other hand, if there is an increase in income levels of consumers.
Then there would be an increase in demand for smartphones. This would lead to an increase in the price of smartphones and potentially higher profits for Mr. Darp.
Therefore, a change in the determinants of demand or supply can impact Mr. Darp by either affecting the supply of smartphones or the demand for smartphones, which in turn can affect the price and profitability of his products.
