Question
a) What is the decay factor?
b) What is the percent decrease?
c) Estimate the number of black and white TV's sold in 1999.
Answer:
a. Decay factor = 0.85
b. Percent decrease = 15%
c. 19.363 million TVs were sold
Step-by-step explanation:
Given

Solving (a): The decay factor
An exponential function has the form

Where b is:

By comparison:

Solving (b): Percentage decrease:
Percentage decrease P is calculated as follows:

Substitute 0.85 for b


Convert to percentage


Solving (c): TVs sold in 1999
First, we need to determine the value of t for 1999
In 1997, t= 0
In 1998, t= 1
In 1999, t= 2
So, we substitute 2 for t in:
