School band members need to raise money for new uniforms. some members want to sell energy drinks at a football game but others want to organize a car wash in the school parking lot. based on economics what would be the most influential in making the decision? the labor needed, he consumer appeal, the capital needed, or the value of the resources ?

Between selling energy drinks during the football game and car washing in the parking lot, I think the most important factor is the consumer appeal. During the planning of every business, the first thing to think about is the potential profit which comes from the consumers. Even though you have the capital, resources and labor, if the consumers doesn't need or like the product, you will not get profit from it. The end goal of every entrepreneur is to meet customer satisfaction.

Moreover, they also have to think if customers would want too buy energy drinks during a football game. Maybe for players, they would buy, but not the audience. They don't need energy drinks. On the other hand, students may not afford to have cars especially if it's from their own allowance. So, they have to consider these things first before moving on to the resources, capital, then lastly, the labor.
