- Of the amount Owen spent in September, $135 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in September?
- In which month did Owen spend $180 more than the previous month? Give your answer in this format. (Eg Jan)

(b)
To find an increase in a line graph, look for an increasing slope.
The 2 increasing slopes are from August to September and November to December. Now, find the month when Owen spent $180 more than the previous month.
Amount that Owen spent in August = $125
Amount that Owen spent in September = $405
Amount that Owen spent in September more than August
= 405 - 125
= $280 (x)
Amount that Owen spent in November = $5
Amount that Owen spent in December = $185
Amount that Owen spent in December more than November
= 185 - 5
=
$180 (✓)
The month that Owen spent $180 more than the previous month = Dec
Answer(s): (a) $270; (b) Dec
