The line graph shows the amount of money Archie spent from January to June.
- Of the amount Archie spent in May, $120 was spent on transport and the remaining amount was spent on food. How much did he spend on food in May?
- In which month did Archie spend $140 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Archie spent in May = $540
Amount that Archie spent on food
= 540 - 120
= $420
(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 Archie spent $140 less than the previous month.
Amount that Archie spent in March = $900
Amount that Archie spent in April = $760
Amount that Archie spent in April less than March
= 900 - 760
=
$140 (✓)
Amount that Archie spent in April = $760
Amount that Archie spent in May = $540
Amount that Archie spent in May less than April
= 760 - 540
= $220 (x)
The month that Archie spent $140 more than the previous month = Apr
Answer(s): (a) $420; (b) Apr
