Use the high-low method to determine the variable and fixed costs components of Swift Lube's operating cost equation. First identify the formula and calculate the variable cost component (slope). (Round your answer to the nearest cent.) Next identify the formula and compute the fixed cost component (the vertical intercept) using the costs for the highest level of activity. (Round your answers to the nearest whole number.) Total fixed costs Data table
