To find an increase in a line graph, look for an increasing slope.
The 2 increasing slopes are from August to September and November to December. Now, find the month when Jenson spent $140 more than the previous month.
Amount that Jenson spent in August = $149
Amount that Jenson spent in September = $309
Amount that Jenson spent in September more than August
= 309 - 149
= $160 (x)
Amount that Jenson spent in November = $69
Amount that Jenson spent in December = $209
Amount that Jenson spent in December more than November
= 209 - 69
=
$140 (✓)
The month that Jenson spent $140 more than the previous month = Dec
Answer(s): (a) $126; (b) Dec
