The line graph shows the amount of money Andy spent from January to June.
- Of the amount Andy spent in April, $144 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 Andy spend $140 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Andy spent in April = $520
Amount that Andy spent on food
= 520 - 144
= $376
(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 Andy spent $140 less than the previous month.
Amount that Andy spent in January = $320
Amount that Andy spent in February = $180
Amount that Andy spent in February less than January
= 320 - 180
=
$140 (✓)
Amount that Andy spent in April = $520
Amount that Andy spent in May = $380
Amount that Andy spent in May less than April
= 520 - 380
= $140 (x)
The month that Andy spent $140 more than the previous month = Feb
Answer(s): (a) $376; (b) Feb
