Answer 1

To find out how many patients the doctor will see in 12 weeks, we first need to determine how many 3-week periods fit into 12 weeks:

\[
\text{Number of 3-week periods in 12 weeks} = \frac{12 \text{ weeks}}{3 \text{ weeks/period}} = 4 \text{ periods}
\]

Next, since the doctor sees 210 patients every 3 weeks, we can multiply the number of patients seen in one period by the number of periods:

\[
\text{Total patients in 12 weeks} = 210 \text{ patients/period} \times 4 \text{ periods} = 840 \text{ patients}
\]

Therefore, the doctor will see **840 patients** in 12 weeks.

The correct response is:
**840 patients**.
