To find an increase in a line graph, look for an increasing slope.
The 2 increasing slopes are from February to March and May to June. Now, find the month when Warren spent $280 more than the previous month.
Amount that Warren spent in February = $395
Amount that Warren spent in March = $535
Amount that Warren spent in March more than February
= 535 - 395
= $140 (x)
Amount that Warren spent in May = $95
Amount that Warren spent in June = $375
Amount that Warren spent in June more than May
= 375 - 95
=
$280 (✓)
The month that Warren spent $280 more than the previous month = Jun
Answer(s): (a) $372; (b) Jun
