Answer with explanation:
Let x be the cost of a pair of sport shoes.
Given : A case of 24 pairs of the same kind of sport shoes cost a little more than $800.
i.e. Cost of same kind 24 pairs = Number of pairs x Cost of a pair
= 24x
The required inequality :

Divide both sides by 24 , we get

But 28 <33.333
It means $28 per pair with tax invluded is not a good estimate of the price.
