First, use front end rounding to estimate each answer. Then find the exact answer.A truck weights 9147 pounds when empty and 21,181 pounds when loaded. What is the weight of the load?
A. estimate: 21,000 - 9100 = 11,900 pounds; exact: 12,034 pounds
B. estimate: 20,000 - 9100 = 10,900 pounds; exact: 12,034 pounds
C. estimate: 21,000 - 9000 = 12,000 pounds; exact: 12,034 pounds
D. estimate: 20,000 - 9000 = 11,000 pounds; exact: 12,034 pounds
