The line graph shows the amount of money Eric spent from January to June.

1. Of the amount Eric spent in May, $187 was spent on food and the remaining amount was spent on transport. How much did he spend on transport in May?
2. In which month did Eric spend $160 less than the previous month? Give your answer in this format. (Eg Jan)

(a)
Amount that Eric spent in May = $280

Amount that Eric spent on transport
= 280 - 187
= $93

(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 $160 less than the previous month.

Amount that Eric spent in March = $740
Amount that Eric spent in April = $580

Amount that Eric spent in April less than March
= 740 - 580
= $160 (✓)

Amount that Eric spent in April = $580
Amount that Eric spent in May = $280

Amount that Eric spent in May less than April
= 580 - 280
= $300 (x)

The month that Eric spent $160 more than the previous month = Apr

Answer(s): (a) $93; (b) Apr
