Last month, 1/9 of dentist's appointments were cancelled, and 3/16 of the remaining appointments were rescheduled. If the dentist had 234 appointments that happened at the scheduled time, how many appointments were either cancelled or rescheduled?

Answer 1

Let x = total appointments

x - 1/9x - 3/16(x-1/9x) = 234

Calculate for x, then subtract 234 from x.
