Question

A case a 24 pairs of same king of sports shoes cost a little more than $800. Explain whether $28 per pair is a good estimate of the price?

Answer 1

Total number of pairs = 24 pairs.

Total cost of 24 pairs = $800 approximately.

Cost of each pair =
`(Total \ cost \ of\ 24 \ pairs )/(Number \ of \ pairs )`

Plugging values in the above formula, we get

Cost of each pair =
`(800)/(24)`

If we divide 800 by 24, we get 33.33 approximately.

But in the given problem, estimated cost is given $28 per pair.

If we subtract 33.33-28, we get $5.33.

So, the estimated cost is $5.33 each pair less than the actual cost of each pair.

Therefore, $28 per pair is not a good estimate of the price.
