[AI-generated answer — Bot GPT 3.5]

Let h be the number of hours Richard needs to work to reach his goal for the week.

The total number of hours Richard has worked so far is 2115 hours.
The total number of hours Richard needs to work for the week is 30 hours.
The equation is 2115 + h = 30
Subtract 2115 from both sides of the equation:
h = 30 - 2115
h = -2085
