Let’s go step by step through each question using the line graph data.
First, let’s list out the hours worked each day from the graph:
- Tuesday: 5 hours
- Wednesday: 9 hours
- Thursday: 6 hours
- Friday: 10 hours
- Saturday: 4 hours
- Sunday: 7 hours
Now solve each problem:
---
1) From Friday to Saturday did the number of hours she worked increase or decrease?
Friday = 10 hours
Saturday = 4 hours
→ 10 to 4 is a
decrease
✔ Answer: Decrease
---
2) What is the total number of hours she worked?
Add all days:
5 (Tue) + 9 (Wed) + 6 (Thu) + 10 (Fri) + 4 (Sat) + 7 (Sun)
= 5+9=14; 14+6=20; 20+10=30; 30+4=34; 34+7=
41
✔ Answer: 41
---
3) Did she work fewer hours on Friday or on Sunday?
Friday = 10
Sunday = 7
→ 7 < 10 → She worked
fewer on Sunday
✔ Answer: Sunday
