The line graph shows the amount of money Eric spent from January to June.
- Of the amount Eric spent in May, $196 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 Eric spend $220 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Eric spent in May = $320
Amount that Eric spent on food
= 320 - 196
= $124
(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 Eric spent $220 less than the previous month.
Amount that Eric spent in March = $840
Amount that Eric spent in April = $620
Amount that Eric spent in April less than March
= 840 - 620
=
$220 (✓)
Amount that Eric spent in April = $620
Amount that Eric spent in May = $320
Amount that Eric spent in May less than April
= 620 - 320
= $300 (x)
The month that Eric spent $220 more than the previous month = Apr
Answer(s): (a) $124; (b) Apr
