Company a:
(4000+2000*2+ 15* 1200+2*500)\( 1+2+ 15+2)
=27000\20
= 1350 (yuan)
The average value of Company A is 1350.
Company b:
(6500+3*4000+23* 1 100+3*500)\( 1+3+23+3)
=45300\30
= 15 10
The final number is 15 10.
The average value of Company B is 15 10.
15 10 is greater than 1350.
So it makes sense.
