The line graph shows the amount of money Mark spent from January to June.
- Of the amount Mark spent in May, $126 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in May?
- In which month did Mark spend $260 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Mark spent in May = $380
Amount that Mark spent on clothes
= 380 - 126
= $254
(b)
To find a decrease in a line graph, look for a decreasing slope.
The 2 decreasing slopes are from March to April and April to May. Now, find the month when Mark spent $260 less than the previous month.
Amount that Mark spent in March = $740
Amount that Mark spent in April = $480
Amount that Mark spent in April less than March
= 740 - 480
=
$260 (✓)
Amount that Mark spent in April = $480
Amount that Mark spent in May = $380
Amount that Mark spent in May less than April
= 480 - 380
= $100 (x)
The month that Mark spent $260 more than the previous month = Apr
Answer(s): (a) $254; (b) Apr
