Determining the Amount of Insulin

Insulin comes in vials labeled with the number of insulin units per cubic centimeter (cc) of fluid. An insulin vial labeled U40 has 40 insulin units per cc of fluid. Tyler’s insulin dosage is 30 insulin units. How many cubic centimeters are needed for Tyler’s dosage?

The unknown quantity, x, is the number of cubic centimeters of fluid needed for Tyler’s dosage. On page 306 is one proportion that can be used to find that quantity.

Given  ratio \left \{ \right.\frac{40  units}{1  cc} =\frac{30  units}{x  cc}

40x = 30(1)

40x = 30

x=\frac{30}{40} =0.75

Tyler’s insulin dosage requires 0.75 cc of the fluid.
