The line graph shows the amount of money Nick spent from January to June.
- Of the amount Nick spent in April, $165 was spent on transport and the remaining amount was spent on food. How much did he spend on food in April?
- In which month did Nick spend $100 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Nick spent in April = $740
Amount that Nick spent on food
= 740 - 165
= $575
(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 $100 less than the previous month.
Amount that Nick spent in January = $380
Amount that Nick spent in February = $280
Amount that Nick spent in February less than January
= 380 - 280
=
$100 (✓)
Amount that Nick spent in April = $740
Amount that Nick spent in May = $520
Amount that Nick spent in May less than April
= 740 - 520
= $220 (x)
The month that Nick spent $100 more than the previous month = Feb
Answer(s): (a) $575; (b) Feb
