Answer:
![L = 30\\R = 21\\M = 42](https://tex.z-dn.net/?f=L%20%3D%2030%5C%5CR%20%3D%2021%5C%5CM%20%3D%2042)
Step-by-step explanation:
Let's assign each person a variable using the first letter of his/her name.
Then we get the following equations based on the information given:
![L + M + R = 93\\L - 9 = R\\M = 2R](https://tex.z-dn.net/?f=L%20%2B%20M%20%2B%20R%20%3D%2093%5C%5CL%20-%209%20%3D%20R%5C%5CM%20%3D%202R)
Then we can use substitution:
![L + M + R = 93\\L + (2R) + R = 93\\L + 3R = 93](https://tex.z-dn.net/?f=L%20%2B%20M%20%2B%20R%20%3D%2093%5C%5CL%20%2B%20%282R%29%20%2B%20R%20%3D%2093%5C%5CL%20%2B%203R%20%3D%2093)
Rearrange the second equation:
![L - R = 9](https://tex.z-dn.net/?f=L%20-%20R%20%3D%209)
Multiple the equation by 3:
![3L - 3R = 27](https://tex.z-dn.net/?f=3L%20-%203R%20%3D%2027)
Combine the equations to solve for a single variable (L):
![L + 3L = 4L\\3R - 3R = 0\\93 + 27 = 120](https://tex.z-dn.net/?f=L%20%2B%203L%20%3D%204L%5C%5C3R%20-%203R%20%3D%200%5C%5C93%20%2B%2027%20%3D%20120)
Then we have a new equation:
![4L = 120\\L = 30](https://tex.z-dn.net/?f=4L%20%3D%20120%5C%5CL%20%3D%2030)
Use substitution to get the rest:
![L - 9 = R\\(30) - 9 = R\\R = 21\\\\M = 2R\\M = 2(21)\\M = 42](https://tex.z-dn.net/?f=L%20-%209%20%3D%20R%5C%5C%2830%29%20-%209%20%3D%20R%5C%5CR%20%3D%2021%5C%5C%5C%5CM%20%3D%202R%5C%5CM%20%3D%202%2821%29%5C%5CM%20%3D%2042)

Answer:
He put $1,183 for the computer
Step-by-step explanation:
first you have to multiply 16.25 time 13 and then multiply that with 14 since there is 14 days in two weeks. And then that with .4.
And you'll get 1,183
