Question

The dosage for a medicine calls for 2cc for every 90 lbs of body weight. At this rate, how much medicine would a 135 lb patient receive?

a) 3 cc
b) 4 cc
c) 2.5 cc
d) 6 cc

Answer 1

A 135 lb patient would receive 3cc of medicine.

Step-by-step explanation:

The dosage for the medicine is 2cc for every 90 lbs of body weight. To find out how much medicine a 135 lb patient would receive, we need to set up a proportion.

Let x be the amount of medicine in cc that the 135 lb patient would receive.

The proportion can be set up as:

2 cc / 90 lbs = x cc / 135 lbs

Cross-multiplying gives us:

90x = 2 * 135

90x = 270

x = 270 / 90

x = 3

Therefore, a 135 lb patient would receive 3cc of medicine.
