The line graph shows the amount of money Fred spent from January to June.
- Of the amount Fred spent in March, $192 was spent on clothes and the remaining amount was spent on food. How much did he spend on food in March?
- In which month did Fred spend $180 more than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Fred spent in March = $585
Amount that Fred spent on food
= 585 - 192
= $393
(b)
To find an increase in a line graph, look for an increasing slope.
The 2 increasing slopes are from February to March and May to June. Now, find the month when Fred spent $180 more than the previous month.
Amount that Fred spent in February = $385
Amount that Fred spent in March = $585
Amount that Fred spent in March more than February
= 585 - 385
= $200 (x)
Amount that Fred spent in May = $225
Amount that Fred spent in June = $405
Amount that Fred spent in June more than May
= 405 - 225
=
$180 (✓)
The month that Fred spent $180 more than the previous month = Jun
Answer(s): (a) $393; (b) Jun
