Option aIncrease

All Options:

  • BDecrease
  • CRemain the same
  • DBecome negative

Detailed Solution & Explanation

To understand the relationship between the price of Coffee and the demand for Tea, we need to consider the concept of substitute goods. • When two goods are substitutes, an increase in the price of one good will lead to an increase in the demand for the other good, as consumers switch to the relatively cheaper alternative. • In this case, Coffee and Tea are likely to be substitute goods, as they can serve as alternatives to each other in satisfying the consumer's desire for a hot beverage. • As the price of Coffee increases, it becomes more expensive relative to Tea, leading consumers to switch to Tea, thereby increasing the demand for Tea. The correct answer is based on the law of demand and the concept of substitute goods. • Option B is incorrect because a decrease in demand for Tea would only occur if Coffee and Tea were complementary goods, which is unlikely in this scenario. • Option C is also incorrect because the change in the price of Coffee will have an effect on the demand for Tea, so the demand will not remain the same.
