(b)
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 Oscar spent $300 more than the previous month.
Amount that Oscar spent in August = $271
Amount that Oscar spent in September = $391
Amount that Oscar spent in September more than August
= 391 - 271
= $120 (x)
Amount that Oscar spent in November = $11
Amount that Oscar spent in December = $311
Amount that Oscar spent in December more than November
= 311 - 11
=
$300 (✓)
The month that Oscar spent $300 more than the previous month = Dec
Answer(s): (a) $258; (b) Dec
