The line graph shows the amount of money Peter spent from January to June.
- Of the amount Peter spent in March, $163 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 Peter spend $280 more than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Peter spent in March = $529
Amount that Peter spent on food
= 529 - 163
= $366
(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 Peter spent $280 more than the previous month.
Amount that Peter spent in February = $369
Amount that Peter spent in March = $529
Amount that Peter spent in March more than February
= 529 - 369
= $160 (x)
Amount that Peter spent in May = $69
Amount that Peter spent in June = $349
Amount that Peter spent in June more than May
= 349 - 69
=
$280 (✓)
The month that Peter spent $280 more than the previous month = Jun
Answer(s): (a) $366; (b) Jun
