Management believes that maintenance cost is a mixed cost that depends on machine$-$hours. Use the high$-$low method to estimate the variable and fixed components of this cost. Compute the variable component first and round off to the nearest whole cent. Compute the fixed component second and round off to the nearest whole dollar. These estimates would be closest to: $($Round your intermediate calculations to $2$ decimal places.$)$
