- Of the amount Ethan spent in August, $139 was spent on transport and the remaining amount was spent on food. How much did he spend on food in August?
- In which month did Ethan spend $200 more than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Ethan spent in August = $520
Amount that Ethan spent on food
= 520 - 139
= $381
(b)
To find an increase in a line graph, look for an increasing slope.
The 3 increasing slopes are from July to August, August to September and November to December. Now, find the month when Ethan spent $200 more than the previous month.
Amount that Ethan spent in July = $220
Amount that Ethan spent in August = $520
Amount that Ethan spent in August more than July
= 520 - 220
= $300 (x)
Amount that Ethan spent in August = $520
Amount that Ethan spent in September = $720
Amount that Ethan spent in September more than August
= 720 - 520
=
$200 (✓)
Amount that Ethan spent in November = $440
Amount that Ethan spent in December = $680
Amount that Ethan spent in December more than November
= 680 - 440
= $240 (x)
The month that Ethan spent $200 more than the previous month = Sep
Answer(s): (a) $381; (b) Sep
