BAC and how many beers/shots and weight

I recently got pulled over for a dui, I started drinking at 7 stoped at 9 and got pulled over at 11:15. I did drink about 4 tall boys and one shot and weigh about 180. Im scared beyond belief and my anxiety is at a all time high. I just want to know on average how high my BAC is, im really hoping it’s below a .15!
