The line graph shows the amount of money Eric spent from January to June.
- Of the amount Eric spent in April, $163 was spent on food and the remaining amount was spent on transport. How much did he spend on transport in April?
- In which month did Eric spend $140 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Eric spent in April = $640
Amount that Eric spent on transport
= 640 - 163
= $477
(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 Eric spent $140 less than the previous month.
Amount that Eric spent in January = $220
Amount that Eric spent in February = $80
Amount that Eric spent in February less than January
= 220 - 80
=
$140 (✓)
Amount that Eric spent in April = $640
Amount that Eric spent in May = $500
Amount that Eric spent in May less than April
= 640 - 500
= $140 (x)
The month that Eric spent $140 more than the previous month = Feb
Answer(s): (a) $477; (b) Feb
