Explanation:

Step1: List sales from Day6-11

From the graph: Day6=0, Day7=15, Day8=2, Day9=16, Day10=2, Day11=3

Step2: Calculate total sales

$0 + 15 + 2 + 16 + 2 + 3 = 38$

Step3: Compute daily average

$\text{Average} = \frac{\text{Total Sales}}{\text{Number of Days}} = \frac{38}{6} \approx 6.333$

Step4: Predict 7-day sales

$\text{Predicted Sales} = \text{Average} \times 7 = \frac{38}{6} \times 7 = \frac{266}{6} \approx 44.333$

Step5: Round to nearest whole number

Round $44.333$ to 44

Answer:

Average from Day6 to Day11: $\approx 6.33$ video cameras
Predicted sales over next 7 days: 44 video cameras
