The problem lacks sufficient information to determine the cost of 18 toy cars. Without knowing the price of one or a few toy cars, it is impossible to calculate the cost of 18 toy cars. Therefore, we cannot provide a definitive answer from the given options.
Explanation
Understanding the Problem The question asks for the cost of 18 toy cars, but it does not provide enough information to determine the cost. There is no information about the cost of one toy car or any other number of toy cars. It seems like the question is incomplete or has missing information. We must choose the most plausible answer from the given options.
Analyzing the Options Since we don't have enough information to calculate the exact cost, we'll analyze the given options and see if any of them seem reasonable. The options are $12, $20, $22, and $2.5. Without any context, it's hard to say which is most likely. However, if we assume that the price should be somewhat proportional to the number of cars, we might expect the cost of 18 cars to be higher than a very low price like $2.5.
Concluding the Solution Without additional information, it is impossible to determine the correct answer. However, if we had to make a choice, we would select the option that seems most plausible given the limited information. In this case, we cannot definitively determine the cost of 18 toy cars.
Examples
Imagine you are buying items in bulk, like office supplies or party favors. Knowing the price per item helps you calculate the total cost for a large quantity. This problem illustrates the importance of having enough information to make accurate calculations, whether you're budgeting for a project or estimating expenses for an event. Without the price per item, you can only guess the total cost.
