The line graph shows the amount of money Simon spent from July to December.

1. Of the amount Simon spent in November, $144 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in November?
2. In which month did Simon spend $140 less than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Simon spent in November = $480

Amount that Simon spent on clothes
= 480 - 144
= $336

(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 Simon spent $140 less than the previous month.

Amount that Simon spent in September = $840
Amount that Simon spent in October = $700

Amount that Simon spent in October less than September
= 840 - 700
= $140 (✓)

Amount that Simon spent in October = $700
Amount that Simon spent in November = $480

Amount that Simon spent in November less than October
= 700 - 480
= $220 (x)

The month that Simon spent $140 more than the previous month = Oct

Answer(s): (a) $336; (b) Oct
