7. Eric is buying 40 two-liter bottles of soda for a carnival. The off-brand bottles are $1.25 and the name-brand bottles are $2.00. He spent $57.50 on all of the two liters. How many bottles of each type did he buy? Eric brought bottles of off-brand soda. Eric brought bottles of name-brand soda. Eric can pour 6 large drinks from each two liter bottle. He charges $0.75 per drink. How much profit will he make if he sells all of the purchased soda (both name brand and off-brand)? Remember, it costs him $1.10 for each two liter of off-brand and $2.50 for each two liter of name-brand.
