A certain company that sells only cars and trucks reported that
revenues from car sales in 1997 were down 11 percent from 1996 and revenues
from truck sales in 1997 were up 7 percent from 1996. If total revenues
from car sales and truck sales in 1997 were up 1 percent from 1996, what is
the ratio of revenue from car sales in 1996 to revenue from truck sales in
1996?
