The price decrease ( D ) and the next model's cost ( X - D ) depend on the current model's cost, which is not provided in the question.
The information provided indicates that the next model of the sports car will be priced lower than the current model. However, the exact amount of the price decrease is not specified, and the current model's cost is missing from the question.
To determine the price decrease, we would need the current model's cost. Let's assume the current model costs $X. If the next model is expected to cost less, we can represent the price decrease as a variable, say D . The price of the next model would then be X - D .
If D is given, we can directly calculate the decreased price X - D . If D is not specified, we can't provide an exact answer regarding the price decrease without that information.
To summarize, the price decrease depends on the difference between the current model's cost X and the unspecified price decrease D . The price of the next model can be expressed as X - D , but an exact value requires knowing the current model's cost and the amount of the decrease.
