Answer:
9 in Aynor and 31 in Spartanburg
Step-by-step explanation:
we need to build the following:
A B C
units COST
Aynor 9 =93 + 80*B2 + POWER(B2;2)*7
Spartanburg 31 =147 + 20*B2 + POWER(B2;2)*3
=b2 + b3 = c2 + c3
We stablish that we want to minimize c3
changing cell b2 and b3
with the restriction that must be integer solution and b4 should equal 40
