Here is the complete question (in attachment).

The least price is for Water Spring brand and the greatest price is of Clear Mountain brand.

Step-by-step explanation:

To find the unit price we have to divide the full price with the whole of the quantity.

From least to greatest unit prices are arranged below.

Water Springs $=\frac{19.99}{48}=0.416\$$
Nature's River $=\frac{20.35}{48}=0.423\$$

Forest Air $=\frac{10.49}{24}=0.437\$$
Iceland Springs $=\frac{5.49}{12}=0.457\$$

Clear Mountain $=\frac{11.99}{24}=0.499\$$

In ascending order the number are.

$0.416 < 0.423< 0.437< 0.457< 0.499$

So the least price is for Water Spring brand,and the greatest price is for Clear Mountain brand.
