2.4 / 0.2 = 12 more one-fifths remaining...

$1.00 + 12 *$0.20 = $3.40 [D] _________________ "The price of anything is the amount of life you exchange for it." -Thoreau VP Joined: 10 Jun 2007 Posts: 1464 Followers: 6 Kudos [?]: 142 [0], given: 0 Re: PS: Confused with the question [#permalink] 20 Apr 2008, 11:13 prasannar wrote: A taxicab charges$1.00 for the first one-fifth mile of a trip and $0.20 for each following one-fifth mile or part thereof.

1 + 4*(0.2) + 5*(0.2) + 3*(0.2) = 3.4
