Final answer:
A 4 oz. container is approximately 118.294 mL. With 30 mL already in the container, an additional 88.294 mL is needed to fill it. However, none of the given options (A, B, C, D) match this calculation.
Step-by-step explanation:
The student is asking how many more milliliters are needed to fill a 4 oz. container if there are already 30 mL of a urine sample in it. First, it is necessary to know how many mL are in 4 oz., since the measurements provided are in different units. The conversion is as follows: 1 oz. is approximately 29.5735 mL.
Hence, a 4 oz. container would have a volume of about 4 x 29.5735 mL, which is around 118.294 mL. To find out how much more liquid is needed to fill the container, we subtract the volume already present (30 mL) from the total capacity of the container:
118.294 mL - 30 mL = 88.294 mL
Since the options provided in the question are all significantly lower than the calculated amount, it seems there might either be an error in the question or more context is required for a proper answer.
Therefore, without appropriate options to choose from, none of the given answers (A, B, C, D) are correct based on the conversion and calculations provided.
