- In which month did Andy spend $260 more than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Andy spent in August = $440
Amount that Andy spent on transport

(b)
To find an increase in a line graph, look for an increasing slope.
The 3 increasing slopes are from July to August, August to September and November to December. Now, find the month when Andy spent $260 more than the previous month.
Amount that Andy spent in July = $260
Amount that Andy spent in August = $440
Amount that Andy spent in August more than July
= 440 - 260
= $180 (x)
Amount that Andy spent in August = $440
Amount that Andy spent in September = $700
Amount that Andy spent in September more than August
= 700 - 440
=
$260 (✓)
Amount that Andy spent in November = $480
Amount that Andy spent in December = $640
Amount that Andy spent in December more than November
= 640 - 480
= $160 (x)
The month that Andy spent $260 more than the previous month = Sep
Answer(s): (a) $267; (b) Sep
