(b)
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 Howard spent $200 more than the previous month.
Amount that Howard spent in February = $130
Amount that Howard spent in March = $430
Amount that Howard spent in March more than February
= 430 - 130
= $300 (x)
Amount that Howard spent in May = $90
Amount that Howard spent in June = $290
Amount that Howard spent in June more than May
= 290 - 90
=
$200 (✓)
The month that Howard spent $200 more than the previous month = Jun
Answer(s): (a) $291; (b) Jun
