Answer 1

To determine which labeled point is a viable solution for the inequality \( 25x + 15y \geq 200 \), we can substitute the \( x \) and \( y \) values from each point into the inequality and check if it holds true.

1. For the point \( (2, 3) \): \[ 25(2) + 15(3) = 50 + 45 = 95 \] Check: \( 95 \geq 200 \) (False)

2. For the point \( (20, 11.5) \): \[ 25(20) + 15(11.5) = 500 + 172.5 = 672.5 \] Check: \( 672.5 \geq 200 \) (True)

3. For the point \( (10, 10) \): \[ 25(10) + 15(10) = 250 + 150 = 400 \] Check: \( 400 \geq 200 \) (True)

From the evaluations:

• The point \( (2, 3) \) is not a viable solution.
• The point \( (20, 11.5) \) is a viable solution.
• The point \( (10, 10) \) is also a viable solution.

Thus, both points \( (20, 11.5) \) and \( (10, 10) \) are viable solutions. However, if you need to select only one, then choose \( (20, 11.5) \), as it is a more extreme point in the context.

Final Answer: \( (20, 11.5) \) is a viable solution.
