To find the number of hours Brian worked, we can first subtract the cost of materials from the total amount billed:
Total cost of materials = $30
Total cost of labor = $81.80 - $30 = $51.80
Now, we can divide the total cost of labor by the rate Brian charged per hour:
Number of hours worked = $51.80 / $14 per hour = 3.7 hours
Therefore, Brian worked for 3.7 hours.
