Check it out:
1) The Measure R half-cent sales tax yielded $700 million for transportation last year in LA County;
2) The Los Angeles County Economic Development Corporation says 58% of the proceeds are paid by businesses and visitors;
3) The rest of LA County residents are paying 42% of the $700 million = $290 million;
4) There are 10 million people in LA County so each pays an average of $29/year;
5) $29 a year divided by 365 days = 8 cents a day.

That's not bad for an expanding transit system.
