Brody has his computer repaired at store a. his bill was: initial repair cost= $1200 sales tax of 6 percent= $72.00 gratuity of 15 percent explain how you would calculate the gratuity for the services provided.

I’m guessing that the answer is c, but i’m not sure which grid is being talked about. since 5x5= 25 and 3x3= 9 (which there are no answers for). a is not right because while the ratio is the same, 6/25= 0.24 which is equal to 24% not 30%.
