A convenience sells two brands of orange juice. Brand A contains 8 fluid ounces and costs $1.28. Brand B contains 12 fluid ounces and costs $1.68

Step-by-step explanation:

Brand A: 8(fl oz):$1:28

Brand B: 12:1.68

1)divide each side of the ratio

8:1.28 = 1:0.16

divide 8 by 8, and 1.28 by 8.

12: 1.68 = 1:0.14

divide each side by 12.

so, for brand A, for every one fluid oz it costs $0.16. for brand B, for every one fluid oz, it costs $0.14.

0.16-0.14= 0.02

$0.02 per fluid oz
