The following information reflects its number of appointments and total costs for the first half of the year: Month January February March April May June Number of Appointments 375 325 450 400 175 475 Total Cost $6,350 6,000 6,450 6,600 5,500 6,100 Using the high-low method, calculate the total fixed cost per month and the variable cost per tanning appointment. (Round your "Variable Cost per Unit" answer to 2 decimal places and "Fixed Cost" answer to the nearest dollar amount.) $ Variable Cost per Unit Fixed Cost 0.50 5,863
