at the start of the year a car dealership has the follow cars:
from ford: 12 cars, 6 suvs, 3 trucks
from chevy: 2 cars, 14 suvs, 7 trucks, 9 vans
from dodge: 9 cars, 4 suvs, 14 trucks, 6 vans
express at a matrix
12 6 3 0
2 14 7 9
9 4 14 6
during janruary the dealer sold
from ford: 6 cars, 3 suv, 1 truck, 4 vans
from chevy: 1 car, 12 suvs, 5 trucks, 7 vans
from dodge: 6 cars, 2 suvs, 4 trucks, 2 vans
express sales as matrix
6 3 1 4
1 12 5 7
6 2 4 2
express the dealers final inventory
I subtracted the two and got:
6 3 2 -4
1 2 2 2
3 2 10 4
now my question is: is this question even possible? i answered it how i think it should be done but if ford has 0 vans at the start of the year how can they sell 4 of something they dont have? how can you end up with a negative inventory?
