At an activity level of $8,700$ machine$-$hours in a month, Falks Corporation's total variable production engineering cost is $$728,190$ and its total fixed productior engineering cost is $$232,290.$ What would be the total production engineering cost per machine$-$hour, both fixed and variable, at an activity level of $8,900$ machine$-$hours in a month? Assume that this level of activity is within the relevant range.

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