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

1. Of the amount Seth spent in March, $149 was spent on clothes and the remaining amount was spent on food. How much did he spend on food in March?
2. In which month did Seth spend $100 more than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Seth spent in March = $590

Amount that Seth spent on food
= 590 - 149
= $441

(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 Seth spent $100 more than the previous month.

Amount that Seth spent in February = $370
Amount that Seth spent in March = $590

Amount that Seth spent in March more than February
= 590 - 370
= $220 (x)

Amount that Seth spent in May = $30
Amount that Seth spent in June = $130

Amount that Seth spent in June more than May
= 130 - 30
= $100 (✓)

The month that Seth spent $100 more than the previous month = Jun

Answer(s): (a) $441; (b) Jun
