The line graph shows the amount of money Ian spent from January to June.
- Of the amount Ian spent in February, $150 was spent on transport and the remaining amount was spent on food. How much did he spend on food in February?
- In which month did Ian spend $200 more than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Ian spent in February = $520
Amount that Ian spent on food
= 520 - 150
= $370
(b)
To find an increase in a line graph, look for an increasing slope.
The 3 increasing slopes are from January to February, February to March and May to June. Now, find the month when Ian spent $200 more than the previous month.
Amount that Ian spent in January = $280
Amount that Ian spent in February = $520
Amount that Ian spent in February more than January
= 520 - 280
= $240 (x)
Amount that Ian spent in February = $520
Amount that Ian spent in March = $720
Amount that Ian spent in March more than February
= 720 - 520
=
$200 (✓)
Amount that Ian spent in May = $200
Amount that Ian spent in June = $440
Amount that Ian spent in June more than May
= 440 - 200
= $240 (x)
The month that Ian spent $200 more than the previous month = Mar
Answer(s): (a) $370; (b) Mar
