The greater the daily dose of vitamin C patients take, the greater their
plasma concentration of vitamin C becomes.
This relationship increases at a rate of 0.1 0.002 micromoles per
milligram of daily dose.
By approximately how many micromoles does the plasma concentration
100 and x=200?
increase between x =
Choose 1 answer:
A 0.067
0.15
7.42
The increase in plasma concentration can be calculated using the formula:
Increase = (0.1 + 0.002x) * x
Substitute x = 100:
Increase = (0.1 + 0.002*100) * 100
Increase = (0.1 + 0.2) * 100
Increase = 0.3 * 100
Increase = 30 micromoles
Substitute x = 200:
Increase = (0.1 + 0.002*200) * 200
Increase = (0.1 + 0.4) * 200
Increase = 0.5 * 200
Increase = 100 micromoles
Therefore, the increase in plasma concentration between x = 100 and x = 200 is 100 - 30 = 70 micromoles.
So, the closest answer choice is:
B) 0.067
