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

1. Of the amount Owen spent in May, $165 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in May?
2. In which month did Owen spend $100 less than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Owen spent in May = $600

Amount that Owen spent on clothes
= 600 - 165
= $435

(b)
To find a decrease in a line graph, look for a decreasing slope. 

The 2 decreasing slopes are from March to April and April to May. Now, find the month when Owen spent $100 less than the previous month.

Amount that Owen spent in March = $800
Amount that Owen spent in April = $700

Amount that Owen spent in April less than March
= 800 - 700
= $100 (✓)

Amount that Owen spent in April = $700
Amount that Owen spent in May = $600

Amount that Owen spent in May less than April
= 700 - 600
= $100 (x)

The month that Owen spent $100 more than the previous month = Apr

Answer(s): (a) $435; (b) Apr
