You take a 200 milligram dosage of aspirin. During each subsequent hour, the amount of medication in your bloodstream decreases
shepuryov [24]

Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Step-by-step explanation:

If the amount is decreasing by r%, then the final amount is given by :-

A=P(1-r)^t

, where P = initial value , t= time

Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours

The level of aspirin (mg) will be in your bloodstream in 4 hours = 200(1-0.35)^4

=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg

Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Use the numbers from the original example: $1,000 invested at a 2% interest rate compounded n times per year. Compare the change
damaskus [11]
Given:
P₀ = $1000, the principal
r = 2% = 0.02, the APR

Let the duration be 1 year 
n =  number of compounding intervals per year.
The value after 1 year is
A=P_{0}(1 +  \frac{r}{n} )^{nt} = 1000(1+ \frac{0.02}{n})^{n}

The following table shows the results obtained from the calculator.

     n                   A
------  ------------------
     1   1020.00000
     4   1020.15050
    12   1020.18436
    52  1020.19742
  365  1020.20078
