Some doctors use the formula ND= 1.08T to relate the variables N (the number of patient appointments the doctor schedules in one day), D (the duration of each patient appointment), and T (the total number of minutes the doctor can use to see patients in one day).

(a) Solve the formula for N.

N = 1.08T/D

(b) Use this result to find the number of patient appointments N a doctor should make if she has 6 hours available for patients and each appointment is 15 minutes long. (Round your answer to the nearest whole number).

=> N = 1.08*360/15

=> N = 25.92

=> N = 26  patient
