    OK.. The Bingham tunnel is 50 cents per trip so 1 trip would cost 50 cents, two trips would cost 50 cents times 2 which is $100, 3 trips would cost 50 cents * 3 which is $1.50. So the cost for the Bingham tunnel in general is .50x (x being the number of trips) With the sticker your cost for 1 trip would be 5.50 + .35 , but for two trips it would be 5.50 + .35 *2, for three trips 5.50 + .35 * 3 so in general this trip with the sticker would cost 5.50 + .35x So when would 5.50 + .35x < .50x First thing is to subtract .35 x from both sides 5.50 < .15x then you would divide both side by .15 and you would get 36.666666 < x if you turn this around you get x > 36.666666666 SO... when you take the 37th trip and everyone after that (x > 36.66666) it would be cheaper. to check this out what happens with 36 trips? .50 * 36 = $18.00 5.50 + .35*36 = $18.10 when you get to the 37th trip .50 * 37 = $18.50 5.50 + .35 * 37 = $18.45 *** this one is now cheaper
