The math club raised money for its spring banquet by washing vehicles. The club charged $3 per car and $5 per truck. The club earned a total of total of $ 550 for washing 122 cars and trucks combined. How many cars did the club wash?
3C + 5 T = 550
C+T= 122
PUT IN 1 T= 122-C
3C + 5 (122-C)=550
3C -5C + 610=550
-2C= 550 - 610= -30
C= 15
T= 122-15 = 107
