Answer:
Following are the solution to this question:
Step-by-step explanation:
In the given question, R stands for radio, S stands for stereo, T stands for television
Since the value of Vally Mills as follows: [tex]11 \ R, 10 \ S, 8\ T \ per \ hour[/tex]
The value of Marlin as follows: [tex]7 \ R,12 \ S, 8\ T \ per\ hour[/tex]
The value of Hillsboro as follows: [tex]5 \ R, 3 \ S, 15\ T \ per\ hour[/tex]
Take into account x1-Vally hour Mills, x2-Marlin hours, x3-Hillsboro hours
In point A:
[tex]\to 1335\ R,1550\ S,1850\ T[/tex]
calculate the above equations as follows:
[tex]\to 11 x_1 + 7x_2 +5x_3 =1335\\\to 10x_1 +12x_2 +3x_3 = 1550\\\to 8x_1 +8x_2 +15 x_3 =1850\\[/tex]
In point B:
[tex]\to 1045 \ R, 1220\ S,1470 \ T\\\\[/tex]
calculate the above equations as follows:
[tex]\to 11x_1 +7x_2 +5x_3 =1045\\\to 10x_1 +12x_2 +3 x_3 =1220\\\to 8x_1 +8 x_2 +15 x_3 =1470[/tex]
