Question

An optometrist prescribes tobramycin to a patient with an eye infection. If a 1 L bag contains 160 mg of tobramycin and the patient receives 50 mg of tobramycin, how many mL of fluid did the patient receive? Round to the nearest tenths

Answer 1

The answer is: Rounded 313 ml.

Step-by-step explanation:

If a 1 L bag contains 160 mg of tobramycin and the patient receives 50 mg of tobramycin, to know the milliliters he ingested, first you have to pass the liters to ml, which would be 1000 ml.

Then making a rule of three, we should multiply 50 mg x 1000 ml = 50,000 mg / ml, then divide it by 160 mg, which would be: 50,000 / 160 = 312.5; that rounded would give us the amount of 313 ml.

The answer is: Rounded 313 ml.
