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

1. Of the amount Tim spent in February, $156 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 Tim spend $120 more than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Tim spent in February = $400

Amount that Tim spent on food
= 400 - 156
= $244

(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 Tim spent $120 more than the previous month.

Amount that Tim spent in January = $120
Amount that Tim spent in February = $400

Amount that Tim spent in February more than January
= 400 - 120
= $280 (x)

Amount that Tim spent in February = $400
Amount that Tim spent in March = $520

Amount that Tim spent in March more than February
= 520 - 400
= $120 (✓)

Amount that Tim spent in May = $200
Amount that Tim spent in June = $380

Amount that Tim spent in June more than May
= 380 - 200
= $180 (x)

The month that Tim spent $120 more than the previous month = Mar

Answer(s): (a) $244; (b) Mar
