A bottle of medication contains 16 ml, which is 20% less than a syringe containing the same medication. How much medication does the syringe contain?
18.0 ml.
18.2 ml.
19.2 ml.
20.0 ml.
The Correct Answer is D
To determine how much medication the syringe contains, given that 16 ml is 20% less than the amount in the syringe, we can set up the following equation:
Let x be the amount of medication in the syringe. We know that 16 ml is 20% less than x:
16 = x − 0.2x
This simplifies to:
16=0.8x
Solving for x:
x = 
Therefore, the syringe contains:
20.0 ml.
