A case of 24 pairs of the same kind of sport shoes costs a little more than $800. Explainwhether $28 per pair with tax included is a good estimate of the price.

Answer 1

If we assume that a cost per pair is $28, we get that a cost of 24 pairs is $28x24 = $672. This contradicts to the statement that it costs more than $800. Hence the $28 is not good estimate for the price.

The good estimate for the price with the tax would be $800/24 = $33.33.
