Answer 1

To determine the possible solutions for the number of cats (x) and dogs (y) at Parakeets Pet Store given the conditions:

1. The combined total of cats and dogs cannot exceed 20: \[ x + y \leq 20 \]

2. The number of cats cannot exceed 8: \[ x \leq 8 \]

Now, let’s evaluate each option provided:

1. (8, 12):

   • \( 8 + 12 = 20 \leq 20 \) (satisfies)
   • \( x = 8 \leq 8 \) (satisfies)
   • Valid solution.

2. (18, 0):

   • \( 18 + 0 = 18 \leq 20 \) (satisfies)
   • \( x = 18 \not\leq 8 \) (does not satisfy)
   • Not valid.

3. (12, 8):

   • \( 12 + 8 = 20 \leq 20 \) (satisfies)
   • \( x = 12 \not\leq 8 \) (does not satisfy)
   • Not valid.

4. (0, 18):

   • \( 0 + 18 = 18 \leq 20 \) (satisfies)
   • \( x = 0 \leq 8 \) (satisfies)
   • Valid solution.

5. (9, 11):

   • \( 9 + 11 = 20 \leq 20 \) (satisfies)
   • \( x = 9 \not\leq 8 \) (does not satisfy)
   • Not valid.

6. (6, 14):

   • \( 6 + 14 = 20 \leq 20 \) (satisfies)
   • \( x = 6 \leq 8 \) (satisfies)
   • Valid solution.

7. (7, 15):

   • \( 7 + 15 = 22 > 20 \) (does not satisfy)
   • Not valid.

8. (14, 6):

   • \( 14 + 6 = 20 \leq 20 \) (satisfies)
   • \( x = 14 \not\leq 8 \) (does not satisfy)
   • Not valid.

Putting it all together, the valid solutions are:

• (8, 12)
• (0, 18)
• (6, 14)

So, the final possible solutions are:

• (8, 12)
• (0, 18)
• (6, 14)
