You can
put this solution on YOUR website!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 "x" be number of trips thru the tunnel.
----------------------
INEQUALITY:
sticker costs < per trip cost
550 + 35x < 50x
15x > 550
x > 36 2/3
----------------
# of trips must be at least 37
