Rationale: Step 1: Let Mr. Johnson's pay be x. Step 2: He gives half to family, so he has x/2 left. Step 3: He pays $250 to landlord, leaving him with x/2 - $250. Step 4: He has 3/7 of his pay left, so x/2 - $250 = 3x/7. Step 5: Solve for x: x/2 - $250 = 3x/7. Step 6: Simplify and solve to get x = $3,500. Therefore, the correct answer is B: $3,500. Summary: A: $3,600 - Incorrect. Does not satisfy the given conditions. C: $2,800 - Incorrect. Does not satisfy the given conditions. D: $1,750 - Incorrect. Does not satisfy the given conditions.
