During a 4th of July weekend, 32 vehicles became trapped on the Sunshine Skyway Bridge while it was being repaved. A recent city ordinance decreed that only cars with 4 wheels and trucks with six wheels could be on the bridge at any given time. If there were 148 tires that needed to be replaced to due to damage, how many cars and trucks were involved in the incident?
----------------
f = 4 wheel vehicles
s = 6 wheels
--------------
f + s = 32 --> 4f + 4s = 128
4f + 6s = 148
4f + 4s = 128
---------------- Subtract
2s = 20
s = 10 6 wheelers
f = 22 4 wheelers
