Final answer:
The question pertains to calculating the cost per sheet of aluminum for Tyler's purchase. Other details, such as thermal expansion coefficients and specific heat capacities, are not related to this calculation and are considered irrelevant in this context.
Step-by-step explanation:
The question provided describes a scenario where Tyler, a self-employed sheet metal worker, purchases 25 sheets of aluminum at a cost of $4000 before tax and shipping. To address the question, we need to consider the cost-related calculations and perhaps the physical properties of aluminum if the question relates to thermal expansion or any other physics concept. However, the supplied information seems to be fragments from different contexts, including thermal expansion coefficients, energy specific heat capacity, and a piece of art made from sheet metal. Since these fragments don't directly relate to the cost of aluminum sheets, we can conclude they are not relevant to answering the question at hand.
Without specific metrics to calculate, like tax or shipping costs for the aluminum sheets, all that can be said is that if Tyler buys the 25 sheets at $4000, the cost per sheet is $4000 divided by 25 sheets, resulting in a cost per sheet of $160.
