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 Rael spent $200 less than the previous month.
Amount that Rael spent in September = $740
Amount that Rael spent in October = $540
Amount that Rael spent in October less than September
= 740 - 540
=
$200 (✓)
Amount that Rael spent in October = $540
Amount that Rael spent in November = $420
Amount that Rael spent in November less than October
= 540 - 420
= $120 (x)
The month that Rael spent $200 more than the previous month = Oct
