 So, she says, compared to last year... All in total, the price of our burger rose by 4 cents. $2.22 per burger. Last year was $2.18, an increase of 1.8%. Good compared to last year's over 5% increase. Looking back one more year, prices for these ingredients had risen about 11%. Causing hamburger sticker shock. Adding bacon will cost you an additional 3 cents, a rise of 7.6% from last year. I'm Rebecca Hughes.
