The line graph shows the amount of money Howard spent from January to June.
- Of the amount Howard spent in May, $143 was spent on food and the remaining amount was spent on transport. How much did he spend on transport in May?
- In which month did Howard spend $120 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Howard spent in May = $300
Amount that Howard spent on transport
= 300 - 143
= $157
(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 Howard spent $120 less than the previous month.
Amount that Howard spent in March = $620
Amount that Howard spent in April = $500
Amount that Howard spent in April less than March
= 620 - 500
=
$120 (✓)
Amount that Howard spent in April = $500
Amount that Howard spent in May = $300
Amount that Howard spent in May less than April
= 500 - 300
= $200 (x)
The month that Howard spent $120 more than the previous month = Apr
Answer(s): (a) $157; (b) Apr
