You have vials containing 250 milligrams of aminophylline in 10 milliliters. How many milliliters are required to administer 300 milligrams? options: 10 milliliters 12 milliliters 15 milliliters 25 milliliters

12 milliliters

Step-by-step explanation:

Proportions

Each vial contains 250 milligrams of aminophylline in 10 milliliters. This means the concentration of aminophylline in the vials is 250/10 = 25 milligrams/milliliter.

To administer 300 milligrams of aminophylline, we need to find the number of milliliters according to the concentration calculated above.

If each milliliter adds up to 25 milligrams, then to have 300 milligrams, 300/25 = 12 milliliters of aminophylline vials are needed.

12 milliliters

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is
