A Shopper paid 2.25 for 4.5 pounds of 7.75 for 2.5 pounds of broccoli and 2.45 for 2.5 pounds of pears. What is the unit price of each item she brought? Show your reasoning.

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
