To determine the valid solutions for the number of cats (x) and dogs (y) at Parakeets Pet Store, we need to consider the following constraints:
-
The total number of cats and dogs cannot exceed 20:
\( x + y \leq 20 \) -
The number of cats cannot exceed 8:
\( x \leq 8 \)
Now, we will evaluate each option:
-
(8, 12):
- \( x + y = 8 + 12 = 20 \) (valid since ≤ 20)
- \( x = 8 \) (valid since ≤ 8)
- Valid.
-
(18, 0):
- \( x + y = 18 + 0 = 18 \) (valid since ≤ 20)
- \( x = 18 \) (invalid since > 8)
- Not Valid.
-
(12, 8):
- \( x + y = 12 + 8 = 20 \) (valid since ≤ 20)
- \( x = 12 \) (invalid since > 8)
- Not Valid.
-
(0, 18):
- \( x + y = 0 + 18 = 18 \) (valid since ≤ 20)
- \( x = 0 \) (valid since ≤ 8)
- Valid.
-
(9, 11):
- \( x + y = 9 + 11 = 20 \) (valid since ≤ 20)
- \( x = 9 \) (invalid since > 8)
- Not Valid.
-
(6, 14):
- \( x + y = 6 + 14 = 20 \) (valid since ≤ 20)
- \( x = 6 \) (valid since ≤ 8)
- Valid.
-
(7, 15):
- \( x + y = 7 + 15 = 22 \) (invalid since > 20)
- Not Valid.
-
(14, 6):
- \( x + y = 14 + 6 = 20 \) (valid since ≤ 20)
- \( x = 14 \) (invalid since > 8)
- Not Valid.
Final Valid Solutions:
- (8, 12)
- (0, 18)
- (6, 14)
Thus, the valid responses based on the constraints provided are:
- (8, 12)
- (0, 18)
- (6, 14)
