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 Eric spent $140 less than the previous month.
Amount that Eric spent in September = $740
Amount that Eric spent in October = $600
Amount that Eric spent in October less than September
= 740 - 600
=
$140 (✓)
Amount that Eric spent in October = $600
Amount that Eric spent in November = $500
Amount that Eric spent in November less than October
= 600 - 500
= $100 (x)
The month that Eric spent $140 more than the previous month = Oct
Answer(s): (a) $356; (b) Oct
