A car rental company charges 21 dollars per day and 10 cents per mile. If a car was rented for 2 days how far was it driven if the total bill came to 220 dollars

The car was driven 1780 miles.

If a car was rented for 2 days, there would be a flat rate of $42 ($21 per day * 2 days = $42).

That leaves $178 from the total bill ($220 total - $42 = $178).

Take the $178 divided by $0.10 per mile and that leaves you with 1780 miles ($178 / $0.10 per mile = 1780 miles).
