subtract the parts from the $225 and $361 and divide each by $34 for the interval
$51 to $187 is the range for labor
divide both by $34/hour, units will be hours
51/34=1.5 hours and 187/34=5.5 hours
(1.5 hours, 5.5 hours)

From  %28225-174%29%2F34 = 1.5 hours (minimal time)  to  %28361-174%29%2F34 = 5.5 hours (maximal time) .
