Final answer:
Chet's watch is indeed still under warranty since only 42 days have passed out of the 90-day warranty period, leaving him with 48 days of warranty remaining.
Step-by-step explanation:
The question asks whether Chet's watch is still under warranty six weeks after the purchase and if so, how many days are left on the warranty.
To answer this, first we need to calculate the number of days in six weeks. There are 7 days in a week, so 6 weeks would be:
6 weeks × 7 days/week = 42 days
Since the warranty is for 90 days, we subtract the 42 days that have already passed to determine the remaining days under warranty:
90 days - 42 days = 48 days
Therefore, the watch is still under warranty, and there are 48 days left on the warranty.
The correct answer is A: Yes, it is still under warranty with 48 days left.
