(b)
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 Carl spent $180 more than the previous month.
Amount that Carl spent in July = $240
Amount that Carl spent in August = $500
Amount that Carl spent in August more than July
= 500 - 240
= $260 (x)
Amount that Carl spent in August = $500
Amount that Carl spent in September = $680
Amount that Carl spent in September more than August
= 680 - 500
=
$180 (✓)
Amount that Carl spent in November = $320
Amount that Carl spent in December = $540
Amount that Carl spent in December more than November
= 540 - 320
= $220 (x)
The month that Carl spent $180 more than the previous month = Sep
Answer(s): (a) $327; (b) Sep
