Question 338578
The usual toll charge to use the Bingham tunnel is 50 cents.
 If you purchase a special sticker for $5.50, the toll is only 35 cents.
 At least how many trips through the tunnel are needed before the sticker costs
 less than paying for each trip separately?
:
Let t = no. of trips for sticker to be less than paying for each trip
:
Total cost paying for each trip = .50t
Total cost using the sticker = 5.50
:
.50t > 5.50
t > {{{5.5/.5}}}
t > 11 trips, 12 trip will make the sticker a better deal
:
:
Check this .50*12 = $6
