A taxi cab service charges $3.75 plus $.40 per mile. Molly takes a taxi cab from the local hotel to the airport. If the total charge was $10.95, which equation could be used to determine the number of miles from the hotel to the airport?

(total cost - fee) / price per mile = miles

Step-by-step explanation:

($10.95 - $3.75) / $0.40 = 18

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
