Option D. is the correct answer.

Step-by-step explanation:

In the question, Some brands and their prices are given. We have to convert unit prices and rank the brands from lowest to highest unit prices.

Brand A. 2.5 pounds  =  $1.48

Therefore,  1 pound   =   1.48 ÷ 2.5 = $0.592  per pound

Brand B. 907.18 grams  =  $1.30

First we convert grams to pound. 453.59 grams  = 1 pound

907.18 grams = 977.18 ÷ 453.59 = 2 pounds

∵ 2 pounds = $1.30

∴ 1 pound  =  1.30 ÷ 2 =  $0.65 per pound

Brand C. 50 ounces  =  $1.55

∵  16 ounces = 1 pound

∴  50 ounces  =  50 ÷ 16 = 3.125 pounds.

Since 3.125 pounds = $1.55

∴  1 pound  = 1.55 ÷ 3.125 =  $0.496  per pound

Therefore,  rank of brands from lowest to highest  unit price is :

Brand C : $0.49 < Brand A : $0.592 < Brand B : 0.65

Option D is the answer.
