To find an increase in a line graph, look for an increasing slope.
The 2 increasing slopes are from August to September and November to December. Now, find the month when Warren spent $100 more than the previous month.
Amount that Warren spent in August = $155
Amount that Warren spent in September = $375
Amount that Warren spent in September more than August
= 375 - 155
= $220 (x)
Amount that Warren spent in November = $35
Amount that Warren spent in December = $135
Amount that Warren spent in December more than November
= 135 - 35
=
$100 (✓)
