Problem 1

A business keeps track of the amount it spends on advertising each month and the amount of income it makes that month. The first 10 months have already been plotted in the scatter plot.

scatter plot showing monthly advertising vs monthly income

  1. The point that represents June is at (26,76.5)(26, 76.5). What does this point mean for the business?
  2. In November, the business spent $25,000 on advertising and had an income of $95,000. In December, the business spent $30,000 on advertising and had an income of $105,000. Add these points to the scatter plot.
  3. After looking at this data, would you suggest the business spend more on advertising in January or not? Explain your reasoning.
