The line graph shows the amount of money Caden spent from January to June.

1. Of the amount Caden spent in February, $198 was spent on transport and the remaining amount was spent on food. How much did he spend on food in February?
2. In which month did Caden spend $140 more than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Caden spent in February = $360

Amount that Caden spent on food
= 360 - 198
= $162

(b)
To find an increase in a line graph, look for an increasing slope. 

The 3 increasing slopes are from January to February, February to March and May to June. Now, find the month when Caden spent $140 more than the previous month.

Amount that Caden spent in January = $240
Amount that Caden spent in February = $360

Amount that Caden spent in February more than January
= 360 - 240
= $120 (x)

Amount that Caden spent in February = $360
Amount that Caden spent in March = $500

Amount that Caden spent in March more than February
= 500 - 360
= $140 (✓)

Amount that Caden spent in May = $120
Amount that Caden spent in June = $320

Amount that Caden spent in June more than May
= 320 - 120
= $200 (x)

The month that Caden spent $140 more than the previous month = Mar

Answer(s): (a) $162; (b) Mar
