Answer: The doctor spent 22 days in police custody
Explanation:
Hi, to answer this question we have to write an equation:
The number of days Dr. E. Quation has spent in police custody will be the variable x. We have to multiply it by 3 (3times) and subtract 22.3.
That expression must be equal to Korea’s median age in years (43.7)
Mathematically speaking;
43.7 = 3x-22.3
Solving for x:
43.7+22.3 =3x
66 = 3x
66/3 =x
22=x
The doctor spent 22 days in police custody
