- Twenty campers are doing water-based activities and 40 campers are doing ground-based activities.
Step-by-step explanation:
1. Let x and y represent the numbers of campers doing water- and ground-based activities, respectively.
x + y ≤ 80 . . . . . . a maximum of 80 campers can be accommodated
x ≥ 8 . . . . . . . . . . a minimum of 8 campers should be water-based
y ≥ 5 . . . . . . . . . . a minimum of 5 campers should be ground-based

3. Twenty campers are doing water-based activities and 40 campers are doing ground-based activities.
Answer:
Option A, x ≥ -2
Step-by-step explanation:
<u>Since the line is not dotted, that means that -2 is included. Also, since the darkened part is toward positive infinity, that means that it is ≥.</u>
<u />
So, it is <em>x ≥ -2</em>
Answer: Option A, x ≥ -2
