The line graph shows the amount of money Tom spent from January to June.
- Of the amount Tom spent in May, $138 was spent on transport and the remaining amount was spent on food. How much did he spend on food in May?
- In which month did Tom spend $100 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Tom spent in May = $260
Amount that Tom spent on food
= 260 - 138
= $122
(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 Tom spent $100 less than the previous month.
Amount that Tom spent in March = $560
Amount that Tom spent in April = $460
Amount that Tom spent in April less than March
= 560 - 460
=
$100 (✓)
Amount that Tom spent in April = $460
Amount that Tom spent in May = $260
Amount that Tom spent in May less than April
= 460 - 260
= $200 (x)
The month that Tom spent $100 more than the previous month = Apr
Answer(s): (a) $122; (b) Apr
