(b)
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 Vaidev spent $160 more than the previous month.
Amount that Vaidev spent in January = $140
Amount that Vaidev spent in February = $320
Amount that Vaidev spent in February more than January
= 320 - 140
= $180 (x)
Amount that Vaidev spent in February = $320
Amount that Vaidev spent in March = $480
Amount that Vaidev spent in March more than February
= 480 - 320
=
$160 (✓)
Amount that Vaidev spent in May = $200
Amount that Vaidev spent in June = $460
Amount that Vaidev spent in June more than May
= 460 - 200
= $260 (x)
The month that Vaidev spent $160 more than the previous month = Mar
Answer(s): (a) $193; (b) Mar
