The line graph shows the amount of money Brandon spent from January to June.
- Of the amount Brandon spent in March, $105 was spent on transport and the remaining amount was spent on food. How much did he spend on food in March?
- In which month did Brandon spend $160 more than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Brandon spent in March = $449
Amount that Brandon spent on food
= 449 - 105
= $344
(b)
To find an increase in a line graph, look for an increasing slope.
The 2 increasing slopes are from February to March and May to June. Now, find the month when Brandon spent $160 more than the previous month.
Amount that Brandon spent in February = $189
Amount that Brandon spent in March = $449
Amount that Brandon spent in March more than February
= 449 - 189
= $260 (x)
Amount that Brandon spent in May = $109
Amount that Brandon spent in June = $269
Amount that Brandon spent in June more than May
= 269 - 109
=
$160 (✓)
The month that Brandon spent $160 more than the previous month = Jun
Answer(s): (a) $344; (b) Jun
