The percentage of the initial amount of medicine that will remain in the patient’s bloodstream after 10 hours is, 17.7%.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

Since, The function that models the percentage, y, of an initial dose of medicine remaining in a patient's bloodstream after x hours is given as,

⇒ $y = 100 (0.5)^(x/4)$

Now, if we substitute the value of x as 10 because we need to find the percentage of medicine in the body after 10 hours.

Therefore, the value can be written as,

⇒ $y = 100 (0.5)^(x/4)$

Put x = 10;

⇒ $y = 100 (0.5)^(2.5)\n$

⇒ y = 17.677

⇒ y = 17.7

Thus, the percentage of the initial amount of medicine that will remain in the patient’s bloodstream after 10 hours is 17.7%.

Peter is reading a 193-page book. He has read three pages more than one fourth of the number of pages he hasnt yet read. How many pages has he not yet read? Estimate how many days it will take Peter to finish the book if he reads about 8 pages per day.

Answers

Let n = the number of pages not read
Then the number of pages read = n/4 + 3
Since the total number of pages is 193, we have

n + n/4 + 3 = 193
5n/4 = 190
n = 152
At 8 pages per day it will take 152 pages/ 8 pages/day = 19 days
