Dr. Klostermann has a container filled with nickels that have a value of $51.45. He has 4 other identical containers with nickels. Of the 4 other identical containers, 2 of them are full, 1 of them is 3/4 full, and 1 of them is 1/2 full. Lamar estimates that the total value of all 5 containers of nickels is approximately $250. Which statement best explains why Lamar's estimate is likely an overestimate or an underestimate? A. Dr. Klostermann's estimate is likely an underestimate because 5 × $51 = $255. b. Dr. Klostermann's estimate is likely an underestimate because it is likely that at least one of the other 2 full containers contains more than $51.45. c. Dr. Klostermann's estimate is likely an overestimate because he has just over 4 full containers, and 4 × $50 = $200. D. Dr. Klostermann's estimate is likely an overestimate because it is doubtful that the other full containers are worth exactly $51.45.
