Final answer:
Using the given sales estimation formula, the estimated sales for $800 advertising is $10460, while for $2000 advertising it is $16400.
Step-by-step explanation:
The student's question involves using a linear equation to estimate sales based on advertising spending.
First, let's apply the given equation Sales = $6500 + $4.95 × Advertising to estimate the sales for advertising of $800 and $2000.
- For $800 in advertising: Sales = $6500 + ($4.95 × 800) = $6500 + $3960 = $10460.
- For $2000 in advertising: Sales = $6500 + ($4.95 × 2000) = $6500 + $9900 = $16400.
Thus, with an advertising budget of $800 and $2000, the estimated sales would be $10460 and $16400, respectively.
