Question 999728: julio is deciding between 4 different vendors for a new IT system. Vendor A is less expensive Vendor C. Vendor C is more expensive than Vendor B. Vendor B is less expensive than Vendor D. Vendor D is less expensive than Vendor A. If Julio wants to purchase the least expensive system, which vendor will he pick?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! A < C
C > B which implies that B < C
B < D
D < A
you have A < C, B < C, B < D, D < A
if A < C and D < A, then you have D < A < C
you have B < D, so now you have B < D < A < C
that means that B is the least expensive.
let's see if all the original assumptions are satisfied.
we are left with B < D < A < C
the original assumptions are:
A < C
C > B which implies that B < C
B < D
D < A
A < C is confirmed.
B < C is confirmed.
B < D is confirmed.
B < A is confirmed.
looks like we're good to go.
solution is that B is the least expensive.
julio should pick vendor B.
