To find an increase in a line graph, look for an increasing slope.
The 3 increasing slopes are from July to August, August to September and November to December. Now, find the month when Dylan spent $180 more than the previous month.
Amount that Dylan spent in July = $400
Amount that Dylan spent in August = $680
Amount that Dylan spent in August more than July
= 680 - 400
= $280 (x)
Amount that Dylan spent in August = $680
Amount that Dylan spent in September = $860
Amount that Dylan spent in September more than August
= 860 - 680
=
$180 (✓)
Amount that Dylan spent in November = $320
Amount that Dylan spent in December = $580
Amount that Dylan spent in December more than November
= 580 - 320
= $260 (x)
The month that Dylan spent $180 more than the previous month = Sep
