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 George spent $260 more than the previous month.
Amount that George spent in August = $205
Amount that George spent in September = $485
Amount that George spent in September more than August
= 485 - 205
= $280 (x)
Amount that George spent in November = $85
Amount that George spent in December = $345
Amount that George spent in December more than November
= 345 - 85
=
$260 (✓)
The month that George spent $260 more than the previous month = Dec
Answer(s): (a) $299; (b) Dec
