To take a taxi it costs $3.00 plus an additional $2.00 per mile traveled. You spent exactly $20 on a taxi, which includes the $1 tip you left. How many miles did you travel?

This is a basic algebraic word problem. Make x equal the miles you traveled. multiply that by 2 and add the 3 initial dollars, then add the one dollar tip, finally make all this equal to 20. So your equation should look like this:

2x + 3 + 1 = 20

add the 3 and 1:

2x + 4 =20

move the 4 to the right side:

2x = 16

devide both sides by 2:

x = 8

So you traveled 8 miles.
