Respuesta :

In 3 week, doctor sees = 210 Patients
In 1 week = 210/3 = 70

So, in 12 weeks, it would be: 70 * 12 = 840 

In short, Your Answer would be 840 Patients

Hope this helps!
He would see 840 patients. All you have to do is multiply by 4 because 12/3=4, and multiplying by 4 would give you the number of patients in 12 weeks
