Question

A taxi costs 3 dollars plus an additional 2 dollars per mile traveled \. You spent exactly $20 on taxi which includes the one dollar tip you left. How many miles did you travel?

Answer 1

8 miles

The equation for this relationship is:

3+2x=y (x is no. of miles and y is the total cost without tips of course)

The total cost without the tip is 20-1=19.

Plug 19 in for y:

3+2x=19

2x=16

x=8
