(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 Bryan spent $280 more than the previous month.
Amount that Bryan spent in July = $280
Amount that Bryan spent in August = $380
Amount that Bryan spent in August more than July
= 380 - 280
= $100 (x)
Amount that Bryan spent in August = $380
Amount that Bryan spent in September = $660
Amount that Bryan spent in September more than August
= 660 - 380
=
$280 (✓)
Amount that Bryan spent in November = $260
Amount that Bryan spent in December = $560
Amount that Bryan spent in December more than November
= 560 - 260
= $300 (x)
The month that Bryan spent $280 more than the previous month = Sep
Answer(s): (a) $181; (b) Sep
