At a farmer’s market, Khalid bought 4 pounds of tomatoes and 7 pounds of broccoli for $28. Genevieve bought 5 pounds of tomatoes and 2 pounds of broccoli for $28.50. Let t represent the cost of one pound of tomatoes. Let b represent the cost of one pound of broccoli. Which system of equations will solve for t and b? 4 t + 7 b = 28.50. 5 t + 2 b = 28.00. 5 t + 7 b = 28.50. 4 t + 2 b = 28.00. 4 t + 7 b = 28.00. 5 t + 2 b = 28.50. 5 t + 4 b = 28.50. 7 t + 2 b = 28.00.
