Solution

Solution Steps

Step 1: Locate 25 on the x-axis.

The x-axis represents the number of electronics sold. We are looking for the amount earned when 25 electronics are sold.

Step 2: Draw a vertical line from x = 25 to the line of best fit.

Drawing a vertical line up from 25 on the x-axis to the best-fit line helps us find the corresponding y-value.

Step 3: Draw a horizontal line from the intersection point to the y-axis.

Drawing a horizontal line from the point where the vertical line intersects the best-fit line over to the y-axis allows us to read the corresponding amount earned.

Step 4: Read the value on the y-axis.

The horizontal line intersects the y-axis somewhere between 2900 and 3625. Observing the grid lines, the value appears closest to 2900.
