Please answer the following question by reasoning step-by-step.
John has to hire a lawyer. He pays $1000 upfront. He then gets charged $100 per hour. The lawyer has to work 50 hours in court time. It takes 2 times that long in prep time. His brother pays half the fee. How much did John pay?

8000
The lawyer worked 50 * 2 = 100 hours out of court.

So he worked 100 + 50 = 150 hours total.

That means the hourly time cost 150 * 100 = $15000.

Adding the upfront cost it was 15000 + 1000 = $16000.

His brother paid half so he paid 16000 / 2 = $8000.

.

The answer is 8000
