Answer
# Explanation:
## Step1: Identify the target percentage
The target is to find a city whose percentage of digital - camera users is closest to 77% (the percentage of digital - camera users in the US population).
## Step2: Compare the percentages
Houston: 96%
Las Vegas: 11%
Phoenix: 49%
San Diego: 78%
The difference between 77% and 96% is $|77 - 96|=19$.
The difference between 77% and 11% is $|77 - 11| = 66$.
The difference between 77% and 49% is $|77 - 49|=28$.
The difference between 77% and 78% is $|77 - 78| = 1$.
