The difference in calories between the classic bacon burger (which is 1,350 calories) and cheese pizza (which is 550 calories)if you multiply by five the difference is 4,000 calories. We got that answer by multiplying 1,350 times 5 which is 6,750 and multiplying 550 times 5 to get 2,750. We finally subtracted 6,750 by 2,750 to get 4,000 calories.
