(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 Zane spent $220 more than the previous month.
Amount that Zane spent in July = $200
Amount that Zane spent in August = $340
Amount that Zane spent in August more than July
= 340 - 200
= $140 (x)
Amount that Zane spent in August = $340
Amount that Zane spent in September = $560
Amount that Zane spent in September more than August
= 560 - 340
=
$220 (✓)
Amount that Zane spent in November = $140
Amount that Zane spent in December = $440
Amount that Zane spent in December more than November
= 440 - 140
= $300 (x)
The month that Zane spent $220 more than the previous month = Sep
Answer(s): (a) $199; (b) Sep
