The line graph shows the amount of money Elijah spent from January to June.

1. Of the amount Elijah spent in March, $186 was spent on transport and the remaining amount was spent on food. How much did he spend on food in March?
2. In which month did Elijah spend $280 more than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Elijah spent in March = $528

Amount that Elijah spent on food
= 528 - 186
= $342

(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 $280 more than the previous month.

Amount that Elijah spent in February = $248
Amount that Elijah spent in March = $528

Amount that Elijah spent in March more than February
= 528 - 248
= $280 (x)

Amount that Elijah spent in May = $308
Amount that Elijah spent in June = $588

Amount that Elijah spent in June more than May
= 588 - 308
= $280 (✓)

The month that Elijah spent $280 more than the previous month = Jun

Answer(s): (a) $342; (b) Jun
