The video-rental store charges $2.00 for the first day a rented video is overdue and $1.25 for each day after that. If a person paid $8.25 in late fees, how many days was the video overdue?

Subtract the first day’s late charge from the total: $8.25 – $2.00 = $6.25. Then divide the remainder by $1.25 to determine the number of additional days the video was overdue: $6.25 ÷ $1.25 = 5. Add those 5 days to the first day the video was late, to find that the video was 6 days overdue.
