Use the linear regression models above to answer this question. Estimate the variable cost per treadmill. Round to the nearest dollar. per treadmill producedBreak-Even Analysis The table below contains price-demand and total cost data for the production of treadmills, where p is the wholesale price (in dollars) of a treadmill for an annual demand of a treadmills, and C is the total cost (in dollars) of producing treadmills. p ($) C ($) 2,910 1,450 3,634,000 3,415 1,275 3,782,000 4,645 1,123 4,185,000 5,330 918 4,290,000 Use this data to find a linear regression equation for price-demand data, using I as the independent variable: p = ax +b, where a is rounded to 1 decimal place and b is rounded to the nearest integer. Use this data to find a linear regression model for the cost data, using x as the independent variable: C(x) = cx + d, where c is rounded to the nearest integer and d is rounded to the nearest 10,000.
