Answer:

Solution:

Total words are 170 + 75+60+55=360.

Each week, Sofia is test with 15 words from the list.

Total number of weeks it will take to finish the test is 24.

Average number of weeks in a year is 25 approximately.

Seven weeks are already over, that means 15×7=105 words are covered from the list. Conclusion:

Remaining words are 360—105=255.
