(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 Neave spent $100 more than the previous month.
Amount that Neave spent in January = $300
Amount that Neave spent in February = $480
Amount that Neave spent in February more than January
= 480 - 300
= $180 (x)
Amount that Neave spent in February = $480
Amount that Neave spent in March = $580
Amount that Neave spent in March more than February
= 580 - 480
=
$100 (✓)
Amount that Neave spent in May = $100
Amount that Neave spent in June = $380
Amount that Neave spent in June more than May
= 380 - 100
= $280 (x)
The month that Neave spent $100 more than the previous month = Mar
Answer(s): (a) $310; (b) Mar
