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).
