Answer:
(8,16) (0,22) (10,10)
Step-by-step explanation:
Let x represents the number of hours spent volunteering in school and y represents the number of hours spent volunteering outside of school.
Since each member must spend a minimum of 20 hours doing volunteer work each semester.
The equation forms : ....(1)
Also given is that the number of hours spent volunteering at school activities can be no more than twice the number of hours spent volunteering outside of school, then equation becomes:
.....(2)
So, lets check with each given pair, if they fulfill both equations:
(7,11): is not ≥ 20 - This is false.
(15,6): = 12 - This is false.
(8,16): which is ≥20 and
- This is true.
(12,5): 12 is not ≤ - This is false.
(0,22): and
- This is true.
(10,10): and
- This is true.
