Yaster Outfitters manufactures and sells extreme-cold sleeping bags. The table below shows the price-demand and total cost data, where: p is the wholesale price in dollars) of a sleeping bag for a weekly demand of x sleeping bags C is the total cost (in dollars) of producing x sleeping bags. x (sleeping bags) a . p ($) C ($) 95 240 13,000 120 235 14,300 180 155 18,500 220 50 21,000 Use this data to create regression models to answer the questions below. Price Model Find a quadratic regression equation for the price-demand data, using x as the independent variable. p = a + bx + cx? Round a to the nearest integer, round b to 2 decimal places, and round c to 4 decimal places, Profit Model Use the models computed to find a model for the weekly profit, using x as the independent variable. P(x) = r + x + 3x + x3 NOTE: Do not calculate another regression. Use the fact that profit is revenue minus cost. Round r to the nearest integer, round u to 1 decimal place, rounds to 2 decimal places, and round / to 4 decimal places Question 20 2 pts What is u? Round to 1 decimal place. D Question 21 2 pts What is s? Round to 2 decimal places. D Question 22 2 pts What is t? Round to 4 decimal places. D Question 23 3 pts Use the weekly profit model to estimate the total weekly profit when the weekly production is 137 Round to the nearest dollar. $
