Answer:
not particularly good, but within an order of magnitude
Step-by-step explanation:
Cost per pair is 800/24 = 100/3 ≈ 33. So 28 is off by more than 5, about 16% of the actual value.
For some purposes, an estimate within 16% would be "good." For other purposes, not so good. In many engineering applications, an estimate within 10% is "good enough." In retail applications where profit margins are less than 5%, an estimate that is off by 16% can make the difference between profit and loss.
The estimate is not particularly good, but may be adequate.
Answer:
To keep the sum rational, the addend must also be rational. The square root of a number which is not itself a perfect square is irrational, so A cannot be the answer, because the sum would be irrational. B is a rational number and therefore when added to 0.5 produces another rational number, 0.75

Answer: 2.01
Step-by-step explanation: Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.
Divide the diameter by 2.
