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

1. Of the amount Howard spent in April, $177 was spent on food and the remaining amount was spent on transport. How much did he spend on transport in April?
2. In which month did Howard spend $120 less than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Howard spent in April = $560

Amount that Howard spent on transport
= 560 - 177
= $383

(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 Howard spent $120 less than the previous month.

Amount that Howard spent in January = $160
Amount that Howard spent in February = $40

Amount that Howard spent in February less than January
= 160 - 40
= $120 (✓)

Amount that Howard spent in April = $560
Amount that Howard spent in May = $460

Amount that Howard spent in May less than April
= 560 - 460
= $100 (x)

The month that Howard spent $120 more than the previous month = Feb

Answer(s): (a) $383; (b) Feb
