Management believes that supply cost is a mixed cost that depends on client$-$visits. Use the high$-$low method to estimate the variable and fixed components of this cost. Compute the variable component first. Then compute the fixed component, rounding off to the nearest whole dollar. Those estimates are closest to:

Note: Round your intermediate calculations to $2$ decimal places.
