    My engineering brain says it’s 3.25.

    4% is ~ 5%. 10% of 75 is 7.5. To get the 5% I have to divide it by 2, so 4% of 75 is close to 3.25. I will have to multiply it with some safety coefficient at the end, so the exact value doesn’t matter.

      Mine brain just does 0.75 × 4.

      Thought process was…

      1. Get 1% = 0.75
      2. Double it = 1.5
      3. Double it = 3

      switch the order of the last two terms (the second equality), put the 0.01 in the middle, and it makes a bit more sense when read as calculation steps.

      0.04 * 75 = 4 * 0.01 * 75 = 4 * 0.75
