A factory produces two pesticides, A and B. Pesticide A produces 0.25 kg CO and 0.60 kg SO2 per barrel. Pesticide B produces 0.60 kg CO and 0.20 kg SO2 per barrel. The factory has a maximum of 75 kg C

Let xx be the number of barrels of pesticide A produced per day.
Let yy be the number of barrels of pesticide B produced per day.

Q2: Find a System of inequality

  1. Identify the emissions for each pesticide and the daily limits.

    • Pesticide A: 0.25 kg CO, 0.60 kg SO₂ per barrel.
    • Pesticide B: 0.60 kg CO, 0.20 kg SO₂ per barrel.
    • Maximum CO emission: 75 kg per day.
    • Maximum SO₂ emission: 90 kg per day.
  2. Formulate the inequalities based on the total emissions.

    The total CO emission must be less than or equal to 75 kg:

    0.25x+0.60y≤750.25x + 0.60y \le 75

    The total SO₂ emission must be less than or equal to 90 kg:

    0.60x+0.20y≤900.60x + 0.20y \le 90

    Since the number of barrels cannot be negative:

    x≥0x \ge 0 y≥0y \ge 0

    The system of inequalities is:

    0.25x+0.60y≤750.25x + 0.60y \le 75 0.60x+0.20y≤900.60x + 0.20y \le 90 x≥0x \ge 0 y≥0y \ge 0

    (Note: Graphing the feasible region is not possible in this text-based format.)

    Q3: Would it be legal for the factory to produce 100 barrels of A and 80 barrels of B per day?

  3. Substitute x=100x = 100 and y=80y = 80 into the CO emission inequality.

    0.25(100)+0.60(80)≤750.25(100) + 0.60(80) \le 75 25+48≤7525 + 48 \le 75 73≤7573 \le 75

    This inequality holds true.

  4. Substitute x=100x = 100 and y=80y = 80 into the SO₂ emission inequality.

    0.60(100)+0.20(80)≤900.60(100) + 0.20(80) \le 90 60+16≤9060 + 16 \le 90 76≤9076 \le 90

    This inequality also holds true.

    Since both pollution constraints are satisfied, it would be legal.
    The answer is: Yes, it would be legal.\boxed{\text{Yes, it would be legal.}}

    Q4: Would it be legal for the factory to produce 60 barrels of A and 160 barrels of B per day?

  5. Substitute x=60x = 60 and y=160y = 160 into the CO emission inequality.

    0.25(60)+0.60(160)≤750.25(60) + 0.60(160) \le 75 15+96≤7515 + 96 \le 75 111≤75111 \le 75

    This inequality is false (111 is not less than or equal to 75).

  6. Substitute x=60x = 60 and y=160y = 160 into the SO₂ emission inequality.

    0.60(60)+0.20(160)≤900.60(60) + 0.20(160) \le 90 36+32≤9036 + 32 \le 90 68≤9068 \le 90

    This inequality holds true.

    Since the CO emission constraint is violated, it would not be legal.
    The answer is: No, it would not be legal.\boxed{\text{No, it would not be legal.}}
