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

1. Of the amount Xavier spent in March, $159 was spent on food and the remaining amount was spent on transport. How much did he spend on transport in March?
2. In which month did Xavier spend $220 more than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Xavier spent in March = $635

Amount that Xavier spent on transport
= 635 - 159
= $476

(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 Xavier spent $220 more than the previous month.

Amount that Xavier spent in February = $395
Amount that Xavier spent in March = $635

Amount that Xavier spent in March more than February
= 635 - 395
= $240 (x)

Amount that Xavier spent in May = $255
Amount that Xavier spent in June = $475

Amount that Xavier spent in June more than May
= 475 - 255
= $220 (✓)

The month that Xavier spent $220 more than the previous month = Jun

Answer(s): (a) $476; (b) Jun
