The line graph shows the amount of money Andy spent from July to December.
- Of the amount Andy spent in November, $126 was spent on food and the remaining amount was spent on transport. How much did he spend on transport in November?
- In which month did Andy spend $240 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Andy spent in November = $280
Amount that Andy spent on transport
= 280 - 126
= $154
(b)
To find a decrease in a line graph, look for a decreasing slope.
The 2 decreasing slopes are from September to October and October to November. Now, find the month when Andy spent $240 less than the previous month.
Amount that Andy spent in September = $620
Amount that Andy spent in October = $380
Amount that Andy spent in October less than September
= 620 - 380
=
$240 (✓)
Amount that Andy spent in October = $380
Amount that Andy spent in November = $280
Amount that Andy spent in November less than October
= 380 - 280
= $100 (x)
The month that Andy spent $240 more than the previous month = Oct
Answer(s): (a) $154; (b) Oct
