Solve.The MetroCity shoe company is planning to produce a new running shoe. For the first year, the fixed costs for setting up production are $41,000. The variable costs for producing each running shoe are $30. The revenue for each running shoe is $80. Find the total profit P(x) from the production and sale of x running shoes.
A. P(x) = 30x - 41,000 B. P(x) = 50x - 41,000 C. P(x) = 41,000x + 30 D. P(x) = 80x - 41,000
