Use the image to answer the question.

An illustration shows a scatterplot with 25 points in quadrant 1. The x-axis is labeled daily high temperature and ranges from 60 to 95 degrees. The y-axis is labeled daily sales and ranges from 25 to 95 dollars. The x-axis shows temperature values in 5 degree increments. The y-axis shows sales in 10 dollar increments. The approximate coordinates of the points are as follows: left parenthesis 58 comma 23 right parenthesis, left parenthesis 60 comma 34 right parenthesis, left parenthesis 64 comma 19 right parenthesis, left parenthesis 66 comma 58 right parenthesis, left parenthesis 69 comma 43 right parenthesis, left parenthesis 69 comma 53 right parenthesis, left parenthesis 72 comma 48 right parenthesis, left parenthesis 74 comma 49 right parenthesis, left parenthesis 75 comma 49 right parenthesis, left parenthesis 77 comma 54 right parenthesis, left parenthesis 78 comma 57 right parenthesis, left parenthesis 78 comma 65 right parenthesis, left parenthesis 80 comma 54 right parenthesis, left parenthesis 81 comma 68 right parenthesis, left parenthesis 82 comma 63 right parenthesis, left parenthesis 84 comma 74 right parenthesis, left parenthesis 84.5 comma 67 right parenthesis, left parenthesis 85 comma 80 right parenthesis, left parenthesis 87 comma 74 right parenthesis, left parenthesis 88.5 comma 73.5 right parenthesis, left parenthesis 87.5 comma 95 right parenthesis, left parenthesis 91 comma 76 right parenthesis, left parenthesis 92.5 comma 69 right parenthesis, and left parenthesis 94 comma 86 right parenthesis, and left parenthesis 94.5 comma 80 right parenthesis.

Using the trend line, what whole number could you infer the daily sales amount is when the temperature is 68°? Round your answer to the nearest whole number.

To find the daily sales amount when the temperature is 68°, identify the approximate position of the point on the scatterplot corresponding to this temperature. Since I cannot analyze the image, I will describe how to determine the value based on the information provided:

  1. Find the x-coordinate 68 on the x-axis (temperature).
  2. Draw a vertical line up from the x-coordinate until it intersects with the trend line.
  3. From the intersection point, draw a horizontal line to the left to read off the y-coordinate (sales amount) on the y-axis.

Based on the coordinates given in the text, we can estimate the sales amount at 68° by looking at the sales values of nearby points:

  • At 66°, the sales are approximately 58.
  • At 69°, the sales are between 43 and 53.
  • The general trend suggests that as the temperature increases from 66° to 69°, sales also increase.

Considering this, we could infer that at 68°, the sales amount would likely be around the average of the values at 66° and 69°.

If we average: 58 (at 66°) and, say, 48 (a reasonable estimate at 68°), we get an average of approximately 53.

Thus, the whole number you could infer daily sales amount when the temperature is 68° is approximately $53.
