Let the three apartments be A, B & C
The rent of A is $x
The rent of B is $y
The rent of C is $z
So x + y + z = 1600 .......(1)
Now
Maintenance of A is 20% of x = 0.20x
Maintenance of B is 20% of y = 0.20y
Maintenance of C is 25% of z = 0.25z
0.20x + 0.20y + 0.25z = 345
Multiplying by 100 we get
20x + 20y + 25 z = 34500
Dividing by 5 we get
4x + 4y + 5z = 6900 .......(2)
Monthly fee of A is 10% of x = 0.10x
Monthly fee of B is 20% of y = 0.20 y
Monthly Fee of C is 10% of z = 0.10z
Now
0.10x + 0.20y + 0.10 z= 1820 - 1600
0.10x + 0.20y + 0.10z = 220
Multiplying by 100 we get
10x + 20y + 10z = 22000
Dividing by 10
x + 2y + z = 2200 ....(3)
Making a Matrix of equation (1), (2) & (3)
is the required matrix
Answer:
Predicted Rotten Tomatoes Score = 29.476 + 1.201 * Metascore
Step-by-step explanation:
The image is needed to solve it, I found an image that I think would be the one that adapts to the exercise, which I will attach.
The answer is:
Predicted Rotten Tomatoes Score = 29,476 + 1,201 * Metascore
Because if we follow the red line, we can see that it impacts with the axis of the and a little lower than 30, that is to say that when Metascore is 0, the value must be close to 30 and in this case the only value close to 30 inside the answer is 29,476, so this is the answer.
