Blue tickets cost 3 dollars and red tickets cost 2 dollars. the total amount of money they collected was 80 dollars which sold 37 tickets. what is twice the number of red tickets sold plus half the number of blue tickets

3b + 2(37-b) =80

b = 6    r= 31         2 r + .5 b = 2(31) + .5(6) = 62+3=65
