High-Low Method Luisa Crimini has been operating a beauty shop in a college town for the past 10 years. Recently, Luisa rented space next to her shop and opened a tanning salon. She anticipated that the costs for the tanning service would primarily be fixed, but found that tanning salon costs increased with the number of appointments. Costs for this service over the past 8 months are as follows: Tanning Month Appointments Total Cost January 700 $1,760 February 1,900 $2,170 March 3,200 $2,810 April 2,400 $2,400 May 1,400 $1,800 June 2,400 July 2,110 $2,265 $2,100 $2,620 August 3,100 Required: 1. Which month represents the high point? The low point? High point March Low point April In your calculations, round per unit costs to the nearest cent. 2. Using the high-low method, compute the variable rate for tanning. Compute the fixed cost per month. Round the variable rate per tanning appointment to the nearest cent and use it in your further calculations. Round the fixed cost per month to the nearest dollar and use it in your further calculations. Variable rate for tanning per tanning appointment $ $ 0.56 1,018 Fixed cost per month 3. Using the variable rate and fixed cost, what is the cost formula for tanning services? Total tanning service cost = $2420 + ($0.37 x Number of appointments) 4. Calculate the total predicted cost of tanning services for September for 2,500 appointments using the formula found in Requirement 3. Of that total cost, how much is the total fixed cost for September? How much is the total predicted variable cost for September? If required, round the final answers to the nearest dollar. Total predicted cost for September $ $ 2,362 1,018 Total fixed cost for September Total predicted variable cost for September $ 1,344 5. Which of the following statements is correct when luisa uses the high-low method to estimate the costs? All of the above
