(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 Henry spent $160 more than the previous month.
Amount that Henry spent in July = $220
Amount that Henry spent in August = $340
Amount that Henry spent in August more than July
= 340 - 220
= $120 (x)
Amount that Henry spent in August = $340
Amount that Henry spent in September = $500
Amount that Henry spent in September more than August
= 500 - 340
=
$160 (✓)
Amount that Henry spent in November = $140
Amount that Henry spent in December = $240
Amount that Henry spent in December more than November
= 240 - 140
= $100 (x)
The month that Henry spent $160 more than the previous month = Sep
Answer(s): (a) $220; (b) Sep
