Chapter 4, Problem 27P
During a golf match, a certain number of points are awarded for each eagle and a different number for each birdie. No points are awarded for par. and a certain number of points are deducted for each bogey and a different number deducted for each double bogey (or worse). The newspaper report of an important match neglected to mention what these point values were, but did provide the following table of the results:
| Golfer | Eagles | Birdies | Pars | Bogeys | Doubles | Points |
| A | 1 | 2 | 10 | 1 | 1 | 5 |
| B | 2 | 3 | 11 | 0 | 1 | 12 |
| C | 1 | 4 | 10 | 1 | 0 | 11 |
| D | 1 | 3 | 10 | 2 | 0 | 8 |
From the information in the table write four equations in terms of four unknowns. Solve the equations for the unknown points awarded for eagles and birdies and points deducted for bogeys and double bogeys.

PS
9 Two films are shown on screen A and screen B at a cinema each evening. The numbers
of people viewing the films on 12 consecutive evenings are shown in the back-to-back
stem-and-leaf diagram.

34
7 6 4 0 534
74 1645678
92 71689
Key: 116|4 represents 61 viewers for A and 64 viewers for B
A second stem-and-leaf diagram (with rows of the same width as the previous diagram)
is drawn showing the total number of people viewing films at the cinema on each of
these 12 evenings. Find the least and greatest possible number of rows that this second
diagram could have.
TIP
On the evening when 30 people viewed films on screen A, there could have been as few
as 37 or as many as 79 people viewing films on screen B.
