The line graph shows the amount of money Elijah spent from January to June.
- Of the amount Elijah spent in March, $179 was spent on clothes and the remaining amount was spent on food. How much did he spend on food in March?
- In which month did Elijah spend $100 more than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Elijah spent in March = $488
Amount that Elijah spent on food
= 488 - 179

(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 Elijah spent $100 more than the previous month.
Amount that Elijah spent in February = $328
Amount that Elijah spent in March = $488
Amount that Elijah spent in March more than February
= 488 - 328
= $160 (x)
Amount that Elijah spent in May = $108
Amount that Elijah spent in June = $208
Amount that Elijah spent in June more than May
= 208 - 108
=
$100 (✓)
The month that Elijah spent $100 more than the previous month = Jun
Answer(s): (a) $309; (b) Jun
