insulin comes in 10 cubic centimeter(cc) vials labeled in the number of units of insulin per cubic centimeter of fluid. A vial marked U40 has 40 units of insulin per cubic centimeter of fluid. If a patient needs 33 units of insulin, how much fluid should be drawn into the syringe from the U40 vial?

Respuesta :

Answer:

8.25 cc fluid should be drawn into the syringe from the U40 vial.

Step-by-step explanation:

The amount of a U40 vial insulin fluid is 10 cc.

A vial marked U40 has 40 units of insulin per cubic centimeter of fluid.

Suppose, if a patient needs 33 units of insulin, then [tex]x[/tex] cc fluid should be drawn.

So, according to the ratio of "cubic centimeter" to "the units of insulin", the equation will be.........

[tex]\frac{x}{33}=\frac{10}{40}\\ \\40x=330\\ \\ x=\frac{330}{40}=8.25[/tex]

So, 8.25 cc fluid should be drawn into the syringe from the U40 vial.
