The line graph shows the amount of money Sam spent from January to June.
- Of the amount Sam spent in April, $124 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in April?
- In which month did Sam spend $300 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Sam spent in April = $400
Amount that Sam spent on clothes
= 400 - 124
= $276
(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 Sam spent $300 less than the previous month.
Amount that Sam spent in January = $380
Amount that Sam spent in February = $80
Amount that Sam spent in February less than January
= 380 - 80
=
$300 (✓)
Amount that Sam spent in April = $400
Amount that Sam spent in May = $140
Amount that Sam spent in May less than April
= 400 - 140
= $260 (x)
The month that Sam spent $300 more than the previous month = Feb
Answer(s): (a) $276; (b) Feb
