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.
Yuck. 75 is such a clean number to work with in percentages, it's 3/4 of a hundred
3/4 of 4 is then easy
I'm confused by this statement, the answer is 3. Why do all these extra steps for a wrong answer?
