Acase of 24 pairs of the same kind of sport shoes cost a little more than 800 explain whether 28 per pair with tax included a good estimate of the price

  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.
