Answer :
Final answer:
The weight of the supply cylinder after the refrigerant has been added is 23 lb. 6 oz. This is calculated by first converting the initial weight to oz., subtracting the amount of refrigerant added, and then converting back into lb. and oz.
Explanation:
This question is dealing with simple subtraction in the field of measurement. Let's begin by converting the weights to the same unit for ease of calculation. Since 1 lb. is equivalent to 16 oz., the initial weight of the supply cylinder is 24 lb. 12 oz., which is 24 x 16 + 12 = 396 oz. After we add 22 oz. of refrigerant to the system, that weight will be subtracted from the supply cylinder, leaving us with a final weight of 396 oz. - 22 oz. = 374 oz. Converting this weight back to pounds and ounces, we find that 1 lb. is equivalent to 16 oz., so the whole number quotient is the weight in pounds and the remainder is the weight in ounces. After doing this calculation, we find that 374 oz. is equivalent to 23 lb. with 6 oz. left over. Therefore, the correct answer is d. 23 lb. 6 oz.
