Question

Transcribed Image Text:The equation \( y = x_1^{1/2} x_2^{1/4} \) is given with \( x_2 \) fixed at 81. The cost of input \( x_1 \) is \( w_1 = 5 \), the cost of input \( x_2 \) is \( w_2 = 3 \), and \( p = 10 \).
The task is to determine which expression represents the correct calculation of profits.
Options:
1. \( \pi = x_1^{1/2} x_2^{1/4} - x_1 x_2 \)
2. \( \pi = 10x_1^{1/2} 81^{1/4} - 5x_1 - 3(81) = 30x_1^{1/2} - 5x_1 - 243 \)
3. \( \pi = x_1^{1/2} 81^{1/4} - 5x_1 - 3(81) = 3x_1^{1/2} - 5x_1 - 243 \)
4. \( \pi = x_1^{1/2} 81^{1/4} - x_1 - 81 = 3x_1^{1/2} - x_1 - 81 \)
The question asks to identify the correct expression for profits, given the equations and parameters stated.
