The line graph shows the amount of money Wesley spent from January to June.
- Of the amount Wesley spent in February, $150 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in February?
- In which month did Wesley spend $140 more than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Wesley spent in February = $420
Amount that Wesley spent on clothes
= 420 - 150

(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 Wesley spent $140 more than the previous month.
Amount that Wesley spent in January = $320
Amount that Wesley spent in February = $420
Amount that Wesley spent in February more than January
= 420 - 320
= $100 (x)
Amount that Wesley spent in February = $420
Amount that Wesley spent in March = $560
Amount that Wesley spent in March more than February
= 560 - 420
=
$140 (✓)
Amount that Wesley spent in May = $220
Amount that Wesley spent in June = $440
Amount that Wesley spent in June more than May
= 440 - 220
= $220 (x)
The month that Wesley spent $140 more than the previous month = Mar
Answer(s): (a) $270; (b) Mar
