To find a decrease in a line graph, look for a decreasing slope.
The 2 decreasing slopes are from September to October and October to November. Now, find the month when Jenson spent $100 less than the previous month.
Amount that Jenson spent in September = $680
Amount that Jenson spent in October = $580
Amount that Jenson spent in October less than September
= 680 - 580
=
$100 (✓)
Amount that Jenson spent in October = $580
Amount that Jenson spent in November = $480
Amount that Jenson spent in November less than October
= 580 - 480
= $100 (x)
The month that Jenson spent $100 more than the previous month = Oct
Answer(s): (a) $339; (b) Oct
