Carmen's Bakery recently spent a total of $120 on new equipment, and their average hourly operating costs are $10. Their average hourly receipts are $11. The bakery will soon make back
the amount it invested in equipment. What would the total expenses and receipts both equal?
How many hours will that take?

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
