Gina chooses what she and her sister will watch on Netflix three times as often as her sister does. If her sister watches a total of 24 shows on Netflix per week, and each show is 50 minutes long, how many minutes of Netflix does Gina get to choose? Let's be accurate as possible.

Let g be the number of shows Gina chooses and s be the number her sister chooses. We know that g = 3s and g + s = 24. Substituting the first equation into the second equation, we get 3s + s = 24. Combining like terms, we get 4s = 24. Dividing both sides by 4, we get s = 6. Substituting this value back into g = 3s, we get g = 3 * 6 = 18. Then multiply the number of shows by the length of each show in minutes to find the total number of minutes Gina chooses: 18 shows * 50 minutes / show = 900 minutes.
The answer: 900.
