First, use front end rounding to estimate each answer. Then find the exact answer.The fully loaded car cost $2345 more than the basic model. If the basic model cost $18,439, what did the fully loaded car cost?
A. estimate: $18,000 + $2000 = $20,000; exact: $20,784 B. estimate: $18,400 + $2300 = $20,700; exact: $20,784 C. estimate: $20,000 + $2000 = $22,000; exact: $20,784 D. estimate: $18,000 + $2300 = $20,300; exact: $20,784
