Answer:
The number of Television at the beginning was 90
The number of video cassette recorders at the beginning was 89
Step-by-step explanation:
Selling Price of 1 Television =$360.
Selling Price of 1 video cassette recorders for $270.
Let the number of Television at the beginning=x
Let the number of video cassette recorders at the beginning =y
Opening Stock =$56,430.
Therefore:
- 360x+270y=$56,430.
It sells three quarters of the televisions and one third of the video cassette recorders for a total of $32,310.
270x+90y=32310
We then solve the two equations to obtain x and y.
- 360x+270y=$56,430. (Multiply by 270)
- 270x+90y=32310 (Multiply by 360)
97200x+72900y=15236100
97200x+32400y=11631600
Subtract
40500y=3604500
y=89
Substitute y=89 into 270x+90y=32310 to obtain x
270x+90(89)=32310
270x=32310-8010=24300
x=90
Therefore:
The number of Television at the beginning was 90
The number of video cassette recorders at the beginning was 89
