The line graph shows the amount of money Charlie spent from January to June.
- Of the amount Charlie spent in April, $136 was spent on transport and the remaining amount was spent on food. How much did he spend on food in April?
- In which month did Charlie spend $180 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Charlie spent in April = $460
Amount that Charlie spent on food
= 460 - 136
= $324
(b)
To find a decrease in a line graph, look for a decreasing slope.
The 2 decreasing slopes are from January to February and April to May. Now, find the month when Charlie spent $180 less than the previous month.
Amount that Charlie spent in January = $300
Amount that Charlie spent in February = $120
Amount that Charlie spent in February less than January
= 300 - 120
=
$180 (✓)
Amount that Charlie spent in April = $460
Amount that Charlie spent in May = $360
Amount that Charlie spent in May less than April
= 460 - 360
= $100 (x)
The month that Charlie spent $180 more than the previous month = Feb
Answer(s): (a) $324; (b) Feb
