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

1. Of the amount Fabian spent in February, $155 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 Fabian spend $180 more than the previous month? Give your answer in this format. (Eg Jan)

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

Amount that Fabian spent on food
= 360 - 155
= $205

(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 Fabian spent $180 more than the previous month.

Amount that Fabian spent in January = $220
Amount that Fabian spent in February = $360

Amount that Fabian spent in February more than January
= 360 - 220
= $140 (x)

Amount that Fabian spent in February = $360
Amount that Fabian spent in March = $540

Amount that Fabian spent in March more than February
= 540 - 360
= $180 (✓)

Amount that Fabian spent in May = $180
Amount that Fabian spent in June = $400

Amount that Fabian spent in June more than May
= 400 - 180
= $220 (x)

The month that Fabian spent $180 more than the previous month = Mar

Answer(s): (a) $205; (b) Mar
