1. A cable company charges a flat monthly rate for its customers, plus the same amount for each movie ordered on demand. One customer ordered 6 movies in a month and was charged a total of $104. Another customer ordered 2 movies in a month and was charged a total of $88. What is the cable company's monthly rate ,r? What does the cable company charge for each ordered on demand, m? 2. Maximillian tried to solve the following system of linear equations using linear combinations.
x - 4y =7
3x + 2y = 7

3x + 2y = 7 --> 2(3x + 2y = 7)
2(3x + 2y = 7) --> 6x + 4y = 14

x - 4y = 7
6x + 4y = 14
7x = 7
x=1

3x + 2y = 7
3(1) + 2y = 7
3+2y = 7
2y = 4
y=2

Maximillan's solution is 1,2. The actual solution is 3, -1. What mistake did Maximillan make in his solution?
