Solución: De la primera ley de la termodinámica, el cambio en la energía interna de un gas viene dado por \Delta U=Q+W donde Q es la energía agregada al gas al calentarlo, y W es el trabajo realizado sobre el gas , dado por W=-P\Delta V donde P es la presión del gas y V es el cambio de volumen del gas a medida que se realizaba el trabajo. Convirtiendo la presión de la atmósfera a Pascal, P=1.3atm\cdot\frac{101325Pa}{1atm} P=1317235Pa Sustituyendo los valores, \Delta U=16000-1317235\left(0.200 -0.100\derecha) \Delta U\aprox2828J Respuesta: Opción d

A company is wondering whether to invest £18,000 in a project which would make extra profits of £10,009 in the first year, £8,000 in the second year and £6,000 in the third year. It’s cost of capital is 10% (in other words, it would require a return of at least 10% on its investment). You are required to evaluate the project.

The Humane Society has asked for our help again this week. Currently they are charging $50 for an adoption fee. Unfortunately they just pulled this number out of the air and do not know why they are charging this amount. They would like to charge an amount that covers all the adoption costs – both the variable costs for adoptions as well as the fixed cost for the kennel portion of the Humane Shelter operations. We can help them by doing a breakeven analysis. During a client meeting we gathered these facts. There are 2 part-time employees that each earn $1000 per month. The utilities for the kennel area (water, electricity) are $200 per month. The average food cost for animals in the kennel is $800 per month. In addition, each animal that is adopted receives a rabies vaccination that costs $4 and is micro-chipped that costs $6. At the current cost of $50, how many animals must be adopted to break-even? What would break-even be at a $60 adoption fee? What would break-even be if the fee were lowered to $40? The newspaper has suggested that the Humane Society advertise to increase pet adoptions. The package that they have recommended costs $1000 for a very small ad run every day for a month. If the Humane Society does this extra advertising, how will it affect breakeven? Based on what you have learned about elasticity, what price do you recommend for the adoption fee?
