I believe the exact answer is 3.91
First of all: Note that this is a linear relationship. If you start at any x and increase x by 2, by how much does y decrease? Verify that this decrease is the same for any two adjacent x-values. Can you figure out the slope of this straight line by doing that? Now think about the y-value you'd get if you were to decrease x not by 2, but by 1.
Using an exponential function, it is found that the multiplier used to predict the amount of medication remaining 2 hours after the peak level is of 0.6889.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, we have that the decay rate is of r = 0.17, hence:

After 2 hours, the multiplier is given by:

Answer:
Two pieces of furniture.
Step-by-step explanation:
3 hours times 1 piece of furniture every 3/4 hours:
3 ·
=
=
= 2.25
Assuming that pieces of furniture cannot be sold in parts, 2 whole pieces of furniture will be sold in 3 hours.
25% of 88 =
0.25 × 88 = 22
88 + 22 = 110
Answer = 110
Hope this helped☺☺
