To estimate the price of one share of stock after 20 years using the equation \( y = 200 - 8x \), we need to substitute \( x = 20 \) into the equation:
\[
y = 200 - 8(20)
\]
Calculating \( 8(20) \):
\[
8(20) = 160
\]
Now substitute back into the equation:
\[
y = 200 - 160
\]
\[
y = 40
\]
Thus, the best estimate of the price of one share of stock after 20 years is **$40.00**.
The answer is **B. $40.00**.
\[
y = 200 - 8(20)
\]
Calculating \( 8(20) \):
\[
8(20) = 160
\]
Now substitute back into the equation:
\[
y = 200 - 160
\]
\[
y = 40
\]
Thus, the best estimate of the price of one share of stock after 20 years is **$40.00**.
The answer is **B. $40.00**.
