To determine the expected number of smartphones in the U.S. for 4.5 years since 2017 using the equation \( y + 9.5x + 257 \), we need to identify what \( x \) represents. In this context, \( x \) likely represents the number of years since 2017.
Since we want to find the value after 4.5 years since 2017, we have:
\[
x = 4.5
\]
Now, we can plug this value into the equation to calculate the expected number of smartphones \( y \):
\[
y + 9.5(4.5) + 257
\]
Calculating \( 9.5 \times 4.5 \):
\[
9.5 \times 4.5 = 42.75
\]
Now substituting back into the equation:
\[
y + 42.75 + 257
\]
Adding \( 42.75 \) and \( 257 \):
\[
y + 299.75
\]
Thus, the expected number of smartphones \( y \) would be:
\[
y + 299.75
\]
To find a specific number, we would need the value of \( y \) from our equation. If \( y \) were initially given or defined in another context, please provide that number to calculate the total. Otherwise, the expected number of smartphones in the U.S. would be \( y + 299.75 \).
