- Of the amount Dylan spent in November, $160 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in November?
- In which month did Dylan spend $160 less than the previous month? Give your answer in this format. (Eg Jan)

(b)
To find a decrease in a line graph, look for a decreasing slope.
The 2 decreasing slopes are from September to October and October to November. Now, find the month when Dylan spent $160 less than the previous month.
Amount that Dylan spent in September = $720
Amount that Dylan spent in October = $560
Amount that Dylan spent in October less than September
= 720 - 560
=
$160 (✓)
Amount that Dylan spent in October = $560
Amount that Dylan spent in November = $260
Amount that Dylan spent in November less than October
= 560 - 260
= $300 (x)
The month that Dylan spent $160 more than the previous month = Oct
