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

1. Of the amount Caden spent in October, $184 was spent on transport and the remaining amount was spent on food. How much did he spend on food in October?
2. In which month did Caden spend $200 less than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Caden spent in October = $620

Amount that Caden spent on food
= 620 - 184
= $436

(b)
To find a decrease in a line graph, look for a decreasing slope. 

The 2 decreasing slopes are from July to August and October to November. Now, find the month when Caden spent $200 less than the previous month.

Amount that Caden spent in July = $380
Amount that Caden spent in August = $180

Amount that Caden spent in August less than July
= 380 - 180
= $200 (✓)

Amount that Caden spent in October = $620
Amount that Caden spent in November = $520

Amount that Caden spent in November less than October
= 620 - 520
= $100 (x)

The month that Caden spent $200 more than the previous month = Aug

Answer(s): (a) $436; (b) Aug
