Answer:
The average per week flow rate of students to the gym is 2700.
Step-by-step explanation:
Given:
Baruch college has 1000 students in the spring of 2018. 30 percent of the students use the gym twice per week, 70 percent of the students use the gym three times a week.
Now, to find the average per week flow rate of students to the gym.
Total number of students = 1000.
So, 30 percent of the students use the gym twice per week:
[tex]30\%\ of\ 1000\times 2\\\\=\frac{30}{100}\times 1000\times 2\\\\=0.30\times 1000\times 2\\\\=600.[/tex]
Now, 70 percent of the students use the gym three times a week:
[tex]70\%\ of\ 1000\times 3\\\\=\frac{70}{100} \times 1000\times 3\\\\=0.70\times 1000\times 3\\\\=2100.[/tex]
Now, to get the average per week flow rate of students to the gym by adding 30 percent of the students use the gym twice per week and 70 percent of the students use the gym three times a week:
[tex]600+2100[/tex]
[tex]=2700.[/tex]
Therefore, the average per week flow rate of students to the gym is 2700.
