Explanation:

Step1: Find the number of commercials when he watched the most TV last week

From the scatter - plot, when he watched TV the most (the \(x\) - value is the largest among the data points), the number of commercials (\(y\) - value) is \(50\).

Step2: Calculate the number of commercials last night

He saw \(20\) more commercials last night. So we use addition. Let \(y_{last\ night}\) be the number of commercials last night. Then \(y_{last\ night}=50 + 20\).

Answer:

\(70\)
