1. A: Solving the system of equations gives y = -4.5. Since -4.5 is greater than -5, the quantity in Column A is greater.

2. A: The average may be represented as (360°)/5, which equals 72°. Since 72° is greater than 70°, the quantity in Column A is greater.

3. C: The shaded area comprises a total angle measure that may be represented as 0.65(360°), or 234°. Thus, the non-shaded area, which represents the value of d, is equal to the difference of 360° and 234°, or 126°. This value is the same value given for Column B.

4. A: The area of a circle with a radius of 3 is equal to 9π. The area of a semi-circle with a radius of 4 is equal to half of 16π, namely 8π. Thus, the quantity in Column A is greater.

5. A: The amount of time Sarah volunteered was 3 hours, 18 minutes. The amount of time Jan volunteered was 3 hours, 17 minutes. Thus, Sarah's quantity was greater.

6. B: The problem may be modeled as 0.34(360) = 0.075h. Solving for h gives h = 1632, which is less than 1634. Thus, the quantity in Column B is greater.

7. A: The fraction of 76 hours in a week may be represented by the ratio, 76/168, which is approximately 45%. The fraction of 10 hours in a day may be represented by the ratio, 10/24, which is approximately 42%. Thus, the quantity in Column A is greater.

8. C: Since the values of x and y are the same, the difference will equal 0. Thus, the quantities in Columns A and B are equal.

9. C: The value for Column A may be written as 5(6). The value for Column B may be written as 6(5). Both expressions equal 30, thus the quantities for Columns A and B are equal.

10. A: The quantity, given for Column A, may be written as 0.96n, which is greater than 0.95n. Thus, the quantity for Column A is greater.

11. B: The problem may be modeled as 5 = 0.667n, where n ≈ 7.5. Since 15 is greater than 7.5, the quantity in Column B is greater.
