Problem
22. A fire hydrant with a blue cap provides water at a rate of 1,500 gallons per minute. A fire hydrant with a green cap provides water at a rate of 1,000 gallons per minute. A fire hydrant with a purple cap provides water at half the rate of a fire hydrant with a green cap. Part A Write an equation to relate the flow of water from the blue hydrant, \( b \), to the flow from the green hydrant, \( g \).
Solution
Step 1 ：b = 1500
Step 2 ：g = 1000
