To find an increase in a line graph, look for an increasing slope.
The 3 increasing slopes are from January to February, February to March and May to June. Now, find the month when Charlie spent $240 more than the previous month.
Amount that Charlie spent in January = $360
Amount that Charlie spent in February = $600
Amount that Charlie spent in February more than January
= 600 - 360
= $240 (x)
Amount that Charlie spent in February = $600
Amount that Charlie spent in March = $840
Amount that Charlie spent in March more than February
= 840 - 600
=
$240 (✓)
Amount that Charlie spent in May = $540
Amount that Charlie spent in June = $640
Amount that Charlie spent in June more than May
= 640 - 540
= $100 (x)
The month that Charlie spent $240 more than the previous month = Mar
Answer(s): (a) $431; (b) Mar
