Math Problem Statement

This graph shows a café’s coffee sales plotted against the outside temperature over a two-week period.

Estimate the temperature when coffee sales are 1200.

Give your answer as a whole number.

Solution

To estimate the temperature when coffee sales are 1200, you need to look at the graph, locate the point where coffee sales reach 1200 on the vertical axis (y-axis), and find the corresponding temperature on the horizontal axis (x-axis).

Since I cannot view images, please refer to the graph and use the following steps:

  1. Find the value "1200" on the y-axis, which represents the coffee sales.
  2. Draw or trace a horizontal line from this point until it intersects the graph's curve.
  3. From the intersection, trace vertically down to the x-axis to estimate the corresponding temperature.

Could you confirm if you've done this, or upload the graph for a more accurate estimation?

Would you like more details on reading graphs, or help with other questions?

Here are 5 related questions for practice:

  1. How do coffee sales vary with temperature according to this graph?
  2. What could cause coffee sales to increase as temperature changes?
  3. How can you find a more precise estimate if the graph is non-linear?
  4. What is the relationship between the slope of the graph and sales trends?
  5. How would the graph look if coffee sales decreased as the temperature rose?

Tip: When estimating values from graphs, always try to be as accurate as possible by using clear reference points like gridlines or labeled axes.
