Answer:
Using the concept of demand, Mr. Pope's desire for a Rolls Royce car would be considered effective demand, which refers to the willingness and ability to pay for a good or service at the prevailing market price.
However, since his current income and credit limit do not allow him to purchase the car, his demand for the Rolls Royce is not backed by effective purchasing power. In other words, he is not able to pay the market price for the car, which means that his demand is not being translated into actual sales.
Therefore, Mr. Pope's situation can be described as a case of unfulfilled demand, where there is a desire for a good or service but it is not being met due to constraints such as limited income or credit limit. In this case, Mr. Pope may need to increase his income or improve his credit score in order to fulfill his demand for the Rolls Royce car.
