Answer:
To solve this problem, let’s use the following formula:
(1.) A = (D – d)/(365.25), where …
A = the girl’s recalculated age in years as a result of excluding
Saturdays and Sundays.
D = the total number of days the 28-year old girl has lived.
d = the total number of days to be subtracted from D as a result of
excluding Saturdays and Sundays, and …
365.25 = the number of days in a year to account for leap years.
(2.) The actual total number of days D that the 28-year old girl has been alive is equal to:
D = (28 years)(365.25 days/year) = 10,227 days
(3.) Next, there is approximately (365.25 days/year)/(7 days/week) =
52.178571 weeks/year (to 6 decimal places); however, so as to
avoid needlessly “splitting hairs,” we’ll use the fact that there is a
total of 52 full weeks in a year.
Note: What I mean by needlessly “splitting hairs” is that there is no need to base our calculations on the more accurate 52.178571 weeks/year rather than the nice, popular integral amount of 52 weeks/year, because when someone gives his or her age, he or she normally gives a whole number amount, e.g., 28 years old; In other words, he or she does not normally say, “28 years, 5 months, 4 days”!
Each of the 52 full weeks has seven (7) days (from Sunday till Saturday) which includes one Saturday and one Sunday;therefore, ...
52 Saturdays + 52 Sundays = 104 days is to be excluded per year in the recalculation of the girl’s age.
Since the girl is 28 years old, we have a total of:
d = (104 days/year)(28 years) = 2,912 total days is to be excluded in the recalculation of the girl’s age.
(4.) Therefore, the girl’s recalculated age, A, if we exclude Saturdays and Sundays is:
A = (D – d)/365.25 = (10,227 days – 2,912 days)/(365.25 days/year)
= 7,315 days/(365.25 days/year)
= 20.027 years (to 3 decimal places)
= 20 years old will be the recalculated age of the 28-year old girl if we
exclude Saturdays and Sundays.
Answer:
20 or 28 years if we do not count
