To find the total cost of producing 20 units of output given the marginal cost function \( MC = \frac{10}{Q} \) and the total cost is 500 when \( Q = 10 \), follow these steps: 1. **Understand the relationship between total cost and marginal cost**: The total cost \( TC \) can be found by integrating the marginal cost \( MC \) and adding the fixed cost \( C \). 2. **Set up the integral for total cost**: \[ TC(Q) = \int MC \, dQ + C \] Given \( MC = \frac{10}{Q} \), we have: \[ TC(Q) = \int \frac{10}{Q} \, dQ + C \] 3. **Find the antiderivative**: \[ \int \frac{10}{Q} \, dQ = 10 \ln|Q| + C \] So, \[ TC(Q) = 10 \ln|Q| + C \] 4. **Use the given information to find the constant \( C \)**: Given that \( TC(10) = 500 \): \[ 500 = 10 \ln(10) + C \] \[ C = 500 - 10 \ln(10) \] 5. **Find the total cost for \( Q = 20 \)**: \[ TC(20) = 10 \ln(20) + C \] Substitute \( C \): \[ TC(20) = 10 \ln(20) + 500 - 10 \ln(10) \] Simplify: \[ TC(20) = 10 (\ln(20) - \ln(10)) + 500 \] \[ TC(20) = 10 \ln\left(\frac{20}{10}\right) + 500 \] \[ TC(20) = 10 \ln(2) + 500 \] 6. **Calculate the numerical value**: \[ \ln(2) \approx 0.6931 \] \[ TC(20) = 10 \times 0.6931 + 500 \] \[ TC(20) = 6.931 + 500 \] \[ TC(20) \approx 506.93 \] So, the total cost of producing 20 units of output is approximately \( 506.93 \). The correct answer is: - \( 506.93 \)

Question

To find the total cost of producing 20 units of output given the marginal cost function MC=10Q MC = \frac{10}{Q} and the total cost is 500 when Q=10 Q = 10 , follow these steps: 1. Understand the relationship between total cost and marginal cost: The total cost TC TC can be found by integrating the marginal cost MC MC and adding the fixed cost C C . 2. Set up the integral for total cost: TC(Q)=MCdQ+C TC(Q) = \int MC \, dQ + C Given MC=10Q MC = \frac{10}{Q} , we have: TC(Q)=10QdQ+C TC(Q) = \int \frac{10}{Q} \, dQ + C 3. Find the antiderivative: 10QdQ=10lnQ+C \int \frac{10}{Q} \, dQ = 10 \ln|Q| + C So, TC(Q)=10lnQ+C TC(Q) = 10 \ln|Q| + C 4. Use the given information to find the constant C C : Given that TC(10)=500 TC(10) = 500 : 500=10ln(10)+C 500 = 10 \ln(10) + C C=50010ln(10) C = 500 - 10 \ln(10) 5. Find the total cost for Q=20 Q = 20 : TC(20)=10ln(20)+C TC(20) = 10 \ln(20) + C Substitute C C : TC(20)=10ln(20)+50010ln(10) TC(20) = 10 \ln(20) + 500 - 10 \ln(10) Simplify: TC(20)=10(ln(20)ln(10))+500 TC(20) = 10 (\ln(20) - \ln(10)) + 500 TC(20)=10ln(2010)+500 TC(20) = 10 \ln\left(\frac{20}{10}\right) + 500 TC(20)=10ln(2)+500 TC(20) = 10 \ln(2) + 500 6. Calculate the numerical value: ln(2)0.6931 \ln(2) \approx 0.6931 TC(20)=10×0.6931+500 TC(20) = 10 \times 0.6931 + 500 TC(20)=6.931+500 TC(20) = 6.931 + 500 TC(20)506.93 TC(20) \approx 506.93 So, the total cost of producing 20 units of output is approximately 506.93 506.93 . The correct answer is: - 506.93 506.93

Solution

Para encontrar el costo total de producir 20 unidades de producción dada la función de costo marginal MC=10Q MC = \frac{10}{Q} y el costo total es 500 cuando Q=10 Q = 10 , sigue estos pasos:

  1. Entiende la relación entre el costo total y el costo marginal: El costo total TC TC se puede encontrar integrando el costo marginal MC MC y agregando el costo fijo C C .

  2. Configura la integral para el costo total: TC(Q)=MCdQ+C TC(Q) = \int MC \, dQ + C Dado MC=10Q MC = \frac{10}{Q} , tenemos: TC(Q)=10QdQ+C TC(Q) = \int \frac{10}{Q} \, dQ + C

  3. Encuentra la antiderivada: 10QdQ=10lnQ+C \int \frac{10}{Q} \, dQ = 10 \ln|Q| + C Entonces, TC(Q)=10lnQ+C TC(Q) = 10 \ln|Q| + C

  4. Usa la información dada para encontrar la constante C C : Dado que TC(10)=500 TC(10) = 500 : 500=10ln(10)+C 500 = 10 \ln(10) + C C=50010ln(10) C = 500 - 10 \ln(10)

  5. Encuentra el costo total para Q=20 Q = 20 : TC(20)=10ln(20)+C TC(20) = 10 \ln(20) + C Sustituye C C : TC(20)=10ln(20)+50010ln(10) TC(20) = 10 \ln(20) + 500 - 10 \ln(10) Simplifica: TC(20)=10(ln(20)ln(10))+500 TC(20) = 10 (\ln(20) - \ln(10)) + 500 TC(20)=10ln(2010)+500 TC(20) = 10 \ln\left(\frac{20}{10}\right) + 500 TC(20)=10ln(2)+500 TC(20) = 10 \ln(2) + 500

  6. Calcula el valor numérico: ln(2)0.6931 \ln(2) \approx 0.6931 TC(20)=10×0.6931+500 TC(20) = 10 \times 0.6931 + 500 TC(20)=6.931+500 TC(20) = 6.931 + 500 TC(20)506.93 TC(20) \approx 506.93

Por lo tanto, el costo total de producir 20 unidades de producción es aproximadamente 506.93 506.93 . La respuesta correcta es: - 506.93 506.93
