DIRECTIONS

For questions 16–20, solve the problem and enter your answer in the grid, as described below, on the answer sheet.

1.  Although not required, it is suggested that you write your answer in the boxes at the top of the columns to help you fill in the circles accurately. You will receive credit only if the circles are filled in correctly.

2.  Mark no more than one circle in any column.

3.  No question has a negative answer.

4.  Some problems may have more than one correct answer. In such cases, grid only one answer.

5.  Mixed numbers such as Images must be gridded as 3.5 or Images.

(If Images is entered into the grid as Images, it will be interpreted as Images, not Images).

6.  Decimal answers: If you obtain a decimal answer with more digits than the grid can accommodate, it may be either rounded or truncated, but it must fill the entire grid.
