Answer to Problem 81E
Thesolution of the given linear equations is
Explanation of Solution
Given information: The given functions are:
Where,
Calculation:
(a) Using graphing utility to find the number of rentals for each movie is given in the following table:
Number of weeks =
| ||
1 | 336 | 42 |
2 | 312 | 60 |
3 | 288 | 78 |
4 | 264 | 96 |
5 | 240 | 114 |
6 | 216 | 132 |
7 | 192 | 150 |
8 | 168 | 168 |
9 | 144 | 186 |
10 | 120 | 204 |
11 | 96 | 222 |
12 | 72 | 240 |
(b) From the above table, it is concluded that the number of rentals of each movie is
same at
Hence, the solution of the given linear equations is
(c) The given equations are:
Hence, the solution of the given linear equations is
(d) From the part(b) and part(c), it is concluded that the solution of the algebraic equations is same.
(e) From the results, it has been found that in 8th week, the demand of each type of movie is same.
