Gratuity of $180
I would multiply the actual repair cost without including tax to determine the gratuity. So just multiply $1200 by 0.15 getting $180.
As an suggestion, calculating 15% in your head is actually quite simple. What you do is calculate 10%, divide that in half, then add together. So for the $1200 example, you have 1200/10 = 120
half of 120 is 60
120 + 60 = 180
So you have a top of $180.
The gratuity for the service provided is $180.
Initial Repair Cost = $1,200
Sales Tax = 6%
Gratuity = 15%
Therefore, based on the above information, the gratuity will be:
= Gratuity percentage × Cost
= 15% × $1200
= 0.15 × $1200
= $180
Therefore, the gratuity is $180
