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 Bryan spent $280 more than the previous month.
Amount that Bryan spent in July = $340
Amount that Bryan spent in August = $600
Amount that Bryan spent in August more than July
= 600 - 340
= $260 (x)
Amount that Bryan spent in August = $600
Amount that Bryan spent in September = $880
Amount that Bryan spent in September more than August
= 880 - 600
=
$280 (✓)
Amount that Bryan spent in November = $460
Amount that Bryan spent in December = $620
Amount that Bryan spent in December more than November
= 620 - 460
= $160 (x)
The month that Bryan spent $280 more than the previous month = Sep
Answer(s): (a) $463; (b) Sep
