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

1. Of the amount Archie spent in November, $196 was spent on transport and the remaining amount was spent on food. How much did he spend on food in November?
2. In which month did Archie spend $160 less than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Archie spent in November = $260

Amount that Archie spent on food
= 260 - 196
= $64

(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 Archie spent $160 less than the previous month.

Amount that Archie spent in September = $660
Amount that Archie spent in October = $500

Amount that Archie spent in October less than September
= 660 - 500
= $160 (✓)

Amount that Archie spent in October = $500
Amount that Archie spent in November = $260

Amount that Archie spent in November less than October
= 500 - 260
= $240 (x)

The month that Archie spent $160 more than the previous month = Oct

Answer(s): (a) $64; (b) Oct
