rented a car․ The car rental company charged $30 per day and $0․25 per mile․ If the total cost was $110, how many miles did you drive?
Let’s solve this step by step․

First, I need to identify the given information:
— Daily rate: $30 per day
— Mileage rate: $0․25 per mile
— Total cost: $110

Wait, the problem doesn’t specify how many days the car was rented․ Let me re-read․․․ Actually, looking at this again, it seems like this might be a one-day rental (a common assumption if not specified), or perhaps there’s missing information․

Actually, let me assume this is for a 1-day rental since no specific number of days is given․

If 1 day:
— Cost for days: $30 × 1 = $30
— Cost for miles: $110 ౼ $30 = $80
— Miles driven: $80 ÷ $0․25 = 320 miles

However, if this were a different number of days, the answer would change․ For example, if 2 days:
— Cost for days: $30 × 2 = $60
— Cost for miles: $110 ౼ $60 = $50
— Miles driven: $50 ÷ $0․25 = 200 miles

Since the problem as stated doesn’t specify the number of days, I’ll provide the answer assuming a 1-day rental, but note that this is an assumption․

Answer: 320 miles (assuming a 1-day rental)
