Since , these events are not independent.

**Answer:**

54,288

**Step-by-step explanation:**

Current model cost is $52,000

The next model is current cost plus 4.4%

4.4% of 52000 equals 2,288

52000+2,288=54,288

The line that slopes downward (in blue) is the boundary line y = -x+5. The inequality y >= -x+5 will have a solid boundary line with shading above this line.

The red line sloping upward is the boundary line y = 3x-4. The inequality y <= 3x-4 means we shade below the red line

The two shaded regions from the inequalities will overlap to get region C.

**Answer: Region C**
