The balance after the third payment is $1715.05.
If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
We are given that;
Amount= $2000
Rate= 1%
Monthly payment = $100
Now,
Plugging these values into the formula, we get:
A = 2000 (1 + 0.01/12)^(12 * 3/12) A
≈ 2015.05
=2015.05 - 100 * 3
= $1715.05
Therefore, by the given interest the answer will be $1715.05

Answer: 97.25 milligrams
Step-by-step explanation:
Given: Curt just drank a cup of coffee to help him stay awake.
The initial amour of caffeine in coffee= 130 milligrams
The rate of decay of caffeine in body = 7%= 0.07
We know that the exponential decay equation with rate r and and time t is given by :-
, where A is the initial value.
Now, the amount of caffeine left in body after 4 hours is given by :-
Hence, after 4 hours 97.25 milligrams will be left.
