Question

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 & trucks w/ 6 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 & trucks were involved in the incident?

Answer 1

Cars + trucks=32
4 cars+6 trucks=148
cars=32-t
4(32-t)+6 trucks=148
128-4 trucks+6 trucks=148
2 trucks=20
trucks=10
cars=22
