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

1. Of the amount Carl spent in February, $105 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in February?
2. In which month did Carl spend $140 more than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Carl spent in February = $340

Amount that Carl spent on clothes
= 340 - 105
= $235

(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 Carl spent $140 more than the previous month.

Amount that Carl spent in January = $120
Amount that Carl spent in February = $340

Amount that Carl spent in February more than January
= 340 - 120
= $220 (x)

Amount that Carl spent in February = $340
Amount that Carl spent in March = $480

Amount that Carl spent in March more than February
= 480 - 340
= $140 (✓)

Amount that Carl spent in May = $200
Amount that Carl spent in June = $320

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

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

Answer(s): (a) $235; (b) Mar
