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 \( y + 299.75 \).
