Fill in the table with the total length of the scarf after 4 and 6 days.
Number of days Length of the scarf (cm)
4
6

Answer 1

To find the total length of the scarf after 4 and 6 days, we can calculate the length based on the initial length and the daily increase.

Zoe has already knitted 6 centimeters and knits 1.5 centimeters each day.

1. **After 4 days**:
- Length after 4 days = Initial length + (Daily increase × Number of days)
- Length after 4 days = 6 cm + (1.5 cm × 4)
- Length after 4 days = 6 cm + 6 cm = 12 cm

2. **After 6 days**:
- Length after 6 days = Initial length + (Daily increase × Number of days)
- Length after 6 days = 6 cm + (1.5 cm × 6)
- Length after 6 days = 6 cm + 9 cm = 15 cm

Now, we can fill in the table:

| Number of days | Length of the scarf (cm) |
|----------------|---------------------------|
| 4 | 12 |
| 6 | 15 |
