B. 5.65b + 12 = 12.13

C. 5.65 (12) + b = 12.13

D. 12b + 5.65 = 12.13

Respuesta :

the anwser is D because you already know that the oranges for 5.65 so that can be alone in the equation. so the only logical anwser would be D

The correct equation to use would be that of option D: 12b + 5.65 = 12.23.

All other options are wrong since they alter the value of the bag of oranges in some form. (The amount paid for the bag of oranges should remain constant as it didn't change at any time during the transaction.)

Following is the solution to 12b + 5.65 = 12.13 should you need it.

12b + 5.65 = 12.13 (given)
12b = 6.48 (subtract 5.65 from both sides)
b = 0.54 (divide both sides by 12)

The price for each bottle of water 54 cents.
