Question

A case of 24 pairs of the same kind of sport shoes cost a little more than $800. Explain whether $28 per pair with tax invluded is a good estimate of the price

Answer 1

Answer:

It is a good estimate for  the shoes because 800 divided by 24 is

800 divided by 24 is 33.33. so $28 per pair plus tax is better than 33.33 plus tax.

Answer 2

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 : $24x>800$

Divide both sides by 24 , we get

$x>33.33333$

But 28 <33.333

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