- In which month did Carl spend $260 more than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Carl spent in August = $440
Amount that Carl spent on food
= 440 - 109
= $331
(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 Carl spent $260 more than the previous month.
Amount that Carl spent in July = $180
Amount that Carl spent in August = $440
Amount that Carl spent in August more than July
= 440 - 180
= $260 (x)
Amount that Carl spent in August = $440
Amount that Carl spent in September = $700
Amount that Carl spent in September more than August
= 700 - 440
=
$260 (✓)
Amount that Carl spent in November = $300
Amount that Carl spent in December = $420
Amount that Carl spent in December more than November
= 420 - 300
= $120 (x)
The month that Carl spent $260 more than the previous month = Sep
Answer(s): (a) $331; (b) Sep
