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

1. Of the amount Nick spent in April, $194 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in April?
2. In which month did Nick spend $220 less than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Nick spent in April = $620

Amount that Nick spent on clothes
= 620 - 194
= $426

(b)
To find a decrease in a line graph, look for a decreasing slope. 

The 2 decreasing slopes are from January to February and April to May. Now, find the month when Nick spent $220 less than the previous month.

Amount that Nick spent in January = $400
Amount that Nick spent in February = $180

Amount that Nick spent in February less than January
= 400 - 180
= $220 (✓)

Amount that Nick spent in April = $620
Amount that Nick spent in May = $420

Amount that Nick spent in May less than April
= 620 - 420
= $200 (x)

The month that Nick spent $220 more than the previous month = Feb

Answer(s): (a) $426; (b) Feb
