Answer 1

Answer:

Brand C, Brand A, Brand B

Step-by-step explanation:

To find the unit price, we divide the price by the number of pounds.

Unit price of:

$\frac{1.48}{2.5} = 0.592$

Brand B: $1.30 for 907.18 grams; 1 pound is approximately 453.59 grams

907.18/453.59 = 2 pounds

Unit price of:

$\frac{1.3}{2} = 0.65$

Brand C: $1.55 for 50 ounces; 1 pound is equal to 16 ounces

50/16 = 3.125 pounds

Unit price of:

$\frac{1.55}{3.125} = 0.496$

From lowest to highest unit price:

C, A and B, so option d.
