Question

Benji has read 5 books so far this year. Benji would like to graph the line that represents the total number of books he will have read, B, after m months, given that he reads 2.5 books each month. He would like the graph to show the number of books read for the next 10 months.
Select from the drop-down menus to correctly complete each statement.

To best show this information, the scale for the B-axis of his graph should go from 0 to at least (blank) , and the m-axis of his graph should go from 0 to at least (blank).

Answer 1

Answer:

• 30
• 10

Explanation:

You want the graph to cover the period from now until 10 months from now (m=10). In that period, Benji will have read 2.5×10 = 25 more books than he has currently. That will bring his total to 5+25 = 30 for the year.

The graph must display numbers on the B axis that go from 0 to 30, and must display numbers on the m axis that go from 0 to 10 in order to cover the period of time described by the problem.
